It's one of the few things that seem like valid martial arts about monk.

If you look at most any fighter, especially in speed based styles, they are generally pretty light on their feet in a spar/fight. Now it is exaggerated in this game, but being able to shift weight to either foot while your in a stance is pretty consequential in most styles of martial arts. Now there are exceptions to this, but in most boxing, northern japanese styles, and korean styles both the front and back leg are used in striking so it pays to have a light foot.

Other than that... monk's animations are all over the place bad from a martial arts standpoint.
