Slicing a high ball
Excellent. Would also note that the ball Fed is hitting is quite high, and that he manages to get his racket hand "higher" than the contact height of the ball before starting "down". To me, that is key in preventing that shot from "floating" too high and without pace.
More of a "curiosity" thing to me is that they all have the racket face significantly more "open" in the backswing than at contact. I also see that with good volleys, and feel that I hit both those shots better if I consciously make that move - as long as that "closing" of the racket face stops after contact.
