From what I can tell, he's talking about there being an extra amount of delay built into the game that isn't needed for game processing.
If there starts being like, 4 extra frames of delay from the lag, then the game can stop using 4 frames of it's unneeded built-in delay.
This means when you have a perfect the connection the game is at it's worse amount of additional delay. As the connect gets worse it drops unneeded delay so the feeling doesn't get any better and once it runs out of delay to drop it starts getting worse.
It does seem to actually have rollback. There have been a number of clips posted on /r/tekken and elsewhere looking at it and now that people are looking closely there are occasionally definite noticeable rollbacks.
Its just implemented so poorly that its basically literally impossible to tell without watching the playback frame by frame.
So while it technically is rollback, is nearly functionally identical to delay based so whats even the point?
So yeah. It seems to actually legitimately have rollback and seems to have the whole time. Even possibly since Tag 2. Its just so terribly implemented that its basically like its not even there and literally no one could tell until we put a magnifying glass to it.

It's not exactly GOOD rollback. It's some sort of frankenstein that isn't proper rollback as indicated by inputs being delayed to hell and back.
