Well Qrow is related to Yang, which might hint at the slightly similar semblances, just like the Schee family.

The barrier thing has been utilized by Ren, Glynda and Cinder, and all of them have a "magic" archetype build.

As for Qrow having many semblances, it is unknown, but possibly could be some sort of power absorbtion thing—just speculating here. (Actually no, that's just dumb, never mind)
