Exactly. The point is that the Y-20 makes a horizontal (although banked) loop while the C-27J does a vertical loop, otherwise known as a loop-de-loop.
That being said, I doubt it's even possible for an aircraft of the Y-20's weight class (especially with current engines) to complete a true loop-de-loop, for the demands put on propulsion and stress on the airframe would likely be too massive.

Foxtrot Alpha said:China And Russia Team Up To Build World's Largest, Most Powerful Chopper.
Currently, the largest and most powerful helicopter to have ever entered production is the gargantuan Mi-26 'Halo' of Russian origin, of which many still serve in governmental and commercial roles around the globe. After decades of the 'Halo' being on top, a new record holder is now said to be on the way, with Russia and China joining forces to make it happen.
This new super-heavy lift class chopper was originally thought to be an outgrowth of the existing, all-weather capable and highly modernized Mi-26T2, but now it seems that it will only borrow a few elements from it, and will overwhelmingly be a 'clean sheet' design.
The fresh design approach is due to China's eye popping requirements. According to Russia, they are said to include almost twice the lifting capacity of the already freakishly powerful and huge Mi-26. That would put the new chopper's lifting ability at somewhere around 80,000lbs! In comparison, the CH-53K 'King Stallion,' America's latest heavy lift design, has a total gross weight just slightly above that figure at 88,000lbs.
Originally, this new Russian-Chinese design was thought to be an outgrowth of the Mi-26T2, although this is now inaccurate as Chinese performance demands are far outside any existing designs' theoretical capabilities.
The Mi-26 can already haul vehicles that are larger than what can fit even into a C-130 Hercules, including everything from armored personnel carriers to dump trucks. Yet China has had a uniquely large demand for heavy under-slung cargo carrying ability, for both construction and logistical purposes and there has been talk for the last decade or two about how a super-heavy lift helicopter could change the way some structures are built. This is especially true for modular vertical oriented structures that are intended to be built fast and replicated quickly, an area of architecture and construction that China continues to be the leader in.
According to Russian reports, multiple Chinese agencies are part of this new mega-chopper procurement program, including those that deal with emergency management and response. This makes some sense as during a natural disaster, or even a time of conflict, moving massive amounts of supplies quickly will be all that much more critical considering China's massive population.
A cost has not been publicly assigned to the program, nor has there been word regarding what percentage Russia will share in the costs of developing such an exotic machine. Regardless of the public absence of some details, Russia says this new design requirements will be locked by the first quarter of 2015.

Russian-Chinese heavy helicopter will have take-off weight of 38 tons - Rogozin
Russia and China have reached an agreement in principle on a joint project to create a heavy transport helicopter, said Deputy Prime Minister Dmitry Rogozin.
"For heavy helicopters moving normally. Treaty to the helicopter on 38 tons," - said to "Interfax-AVN" Rogozin.
According to him, it was decided that "Russia's contribution to the project will be material, our technical capabilities."
Previously CEO of the holding company "Helicopters of Russia" Alexander Mikheyev said "Interfax-AVN" that technical configuration of the Russian-Chinese heavy helicopter will be determined before the end of the year.
"Hopefully, this year we define the technical configuration of the helicopter and the status of the project," - said A.Miheev.
According to him, the Russian-Chinese heavy helicopter is planned to create on the basis of the technological platform of the heaviest in the world of the Mi-26, produced by "Rostvertol" (part of the holding company "Helicopters of Russia").
He noted that the new car will not be analogue or further development of Russian heavy Mi-26 helicopter. "This helicopter will be developed specifically for the Chinese market, to perform the missions that are formulated by various ministries and agencies in China. Primarily the Ministry of Emergency Situations," - said A.Miheev.
