I wish the vid were a little clearer. I can't quite make out what his fee are doing. I'm looking more at his body. What I see is a sudden stop & spin in the opposite direction. No body lean... nothing to show him putting any effort towards stopping his momentum before the change in direction, and nothing to show him pushing off in the orther. And the direction change happens quicker than I'd want. From that, I get the STRONG impression his feet do nothing more than go from a running animation in one direction to a running animation in another.
