The entire purpose of that picture is to go "Ruby looks nothing like Raven, but Yang does have very similar features to Raven and likely is related to her."

By the way, that image was made before the Volume 3 Opening was released. The opening has proven that Raven is Yang's real mother. Yang said that Summer, Taiyang, her mother, and Qrow were on a team together, and the Volume 3 Opening shows an old photo of Summer, Taiyang, Raven, and Qrow standing together.

Also, Raven and Qrow both share the last name Branwen, so they're likely siblings, which would mean that Qrow is Yang's uncle. Ruby just calls him uncle even though they're not related by blood.
