That was my feeling after listening yes. The year is not necessarily 2027 but a timetable exists, and the year were it all happens is closer than 004's normal commissioning date if construction went at a regular pace, hence why the construction was accelerated.
Bar some divine intervention, the 004 CVN will never be ready for active service in 2027, let alone reaching IOC that would've granted the CVN at least certain degree of capabilities to conduct warfighting operations against the enemy.
If anything, I expect the 004 CVN to be comissioned sometime in 2030, assuming that the CVN is launched by late-2027 and having the same duration of fitting out + sea trials as Fujian.
As others have said above - 2027 is a significant year for the PLA as-a-whole, rather than having a specific AR goal for the rebel itself.
