If you catch the ball while moving with both feet in the air, which I'm pretty sure Amile does here, then your pivot foot is the first foot to touch the ground. In this case, his right foot became the pivot. He can pick his pivot foot up before the shot (or a pass), but he can't put it back down on the court before releasing the shot (or a pass). So it wouldn't have been a walk if he jumped off the left foot, but as soon as he put the right foot back down he traveled.
