If Qrow is Raven's brother, they're still biologically related and she still knows him personally. She doesn't need to know he's the brother of her missing mother. He would refer to himself as Yang's uncle even without mentioning she had another mother. She would just assume that Qrow was Summer's brother. Logic, son.
