You can actually fudge the input by rolling 3214K. Typically, though, I hold 3, then dart back to 4 and hit K. The hold can't be too long though or your 14 frame move will become more like an 18 frame move.
Knowing attacks that leave you in crouching state is helpful in certain situations though. For example, after WR H+K, after a WU kick. But overall, you don't want to adapt to only using the move after such attacks, because then you won't know how to use it standalone when you need it.
