If Raven is Yang's mom and Qrow's sister, it explains why Qrow is referred to as "Uncle Qrow" by Yang and Ruby.

Qrow stuck around after Raven left. Yang had literally just been born when Raven left, so there's no way she would know that Summer wasn't her real mom. Qrow behaved as an uncle figure to both girls, and no one bothered to correct them that Qrow is really only Yang's uncle because that would raise all kinds of questions.

Even though Yang knows now, it's not going to change the fact that he was an uncle figure to both of them. Ruby has an uncle-niece bond with Qrow, despite not being blood related. Nothing is going to make her stop considering him her uncle.
