When I first saw the video it appeared he was only trying to hurdle the punter. From different angles, though, it looked intentional; he was aiming for his face.
Normal people wouldn't think they could hurdle over a standing or even a halfway-falling man, especially having just sprinted some distance while wearing full pads.
Maybe he just got a sudden urge to show off his "silly walk" and swing his foot over into the punter's face? Kind of like a little pre-end-zone dance?
