He is addressing your video by commenting on twirling, and player preference in terms of grips. What he’s saying is players tend to hit the same “face” on a certain stroke based more on how the grip feels rather than using the same face. This would seem to indicate that most players would use opposing faces if the grip feels better in a certain position. Federer is merely being used as an example.
