...until I covered his feet/lower part of the body on screen, so I just could see his shoulders and then it was ok. I think he is one of the old dancers still having the expression at shoulder level.
That's an interesting observation!
I've never watched Tete's feet very much before, but I can see where his feet appear to be off the beat. I also notice that Sylvia's feet appear to be right on the beat.
If Tete's thought is to give his partner a dance and he's thinking about putting her feet on the beat, maybe his own footwork becomes secondary in importance.
