Flawless logic except it is not all about last names. It also has to do with Genetics. Red hair is a resessive trait, so it would take a black haired man and a red haired woman to get the black/red hair. So Yang and Ruby may have come from different mothers and seeing as Ruby's is still around (as she has said "My parents" in ep. 1). You're seriously bringing up the rules of genetics and inheritence? It's anime (or at least animesque)!
