That diagram with orbit from Earth's point of view is really cool. You can see Chang'e doing it's normal orbit around the moon, then first burn making the orbit into a highly elliptical orbit with apolune in the retrograde lunar orbit direction, then second burn completes the TEI.
Not sure if the trajectory after separation with re-entry module is correct, but if it is that diagram indicates that the orbiter module will return to lunar sphere of influence when it reaches apogee.

I think you meant perilune?
I believe the diagram shows the trajectory of Chang'e 5 from its launch to its return to Earth.

To make your audience believe you still matter & is center of the universe.
That helps to keep your currency the reserve status quite a bit.
As @Quickie has said, it is the whole trajectory since launch. The red part is what has happened, the green is to be happening.
Now we know when and where Chang'e will land.

Chang'e 5 is still making the small adjustment (its 2 engines fired for only 28 secs) while on the way back to earth.
China Focus: Chang'e-5 completes first orbital correction en route to Earth
BEIJING, Dec. 14 (Xinhua) -- China's Chang'e-5 probe on Monday completed its first orbital correction en route to Earth, according to the China National Space Administration (CNSA).
The orbital correction was conducted at 11:13 a.m. (Beijing Time) when the two 25N engines on the orbiter-returner combination were operational for about 28 seconds.
The CNSA said all systems on the orbiter-returner combination that carries lunar samples are currently in good condition.
The orbiter-returner combination entered the moon-Earth transfer orbit on Sunday.
This simulated image shows the second orbital maneuver and orbital correction of the orbiter-returner combination of China's Chang'e-5 lunar probe.

When the time is right, the orbiter and returner will separate from one another, according to the CNSA. The probe's returner is expected to land at the Siziwang Banner in north China's Inner Mongolia Autonomous Region in mid-December.
Chang'e-5 is one of the most complicated and challenging missions in China's aerospace history. It is also the world's first moon-sample mission in more than 40 years.
The probe, comprising an orbiter, a lander, an ascender and a returner, was launched on Nov. 24, and its lander-ascender combination touched down on the north of the Mons Rumker in Oceanus Procellarum, also known as the Ocean of Storms, on the near side of the moon on Dec. 1. ■
