To me, this preview proves that Qrow already recognized Mercury and Emerald and deduced what's going on. He just can't reveal it to Yang since the right time hasn't come yet.

I mean, he saw Emerald and Mecury in the fight with Amber even before they had the chance to obscure their appearance. He saw them disappearing in thin air, there should be no reason for him to not understand what happens.
