Headcanon: The longer Discord interacts with ponies, the more he begins to relate to them, the more often he begins to walk on four legs. It’s a social mirroring behavior and signals his growing integration into pony society (eh, to the best pony society can accept a giant chaos dragon horse monster, anyway) It makes interacting/talking to ponies easier, to the point where eventually he only goes two-legged to be intimidating and practice his magnificent tap-dance routines
