If you're going by the first theory I listed, maybe the parents gave Ruby and Yang the choice when they got older. Like they sat them down and were like "Now as you may know, your father and I have different last names. We feel you are old enough to pick the last name you want." It is possible anyway. Maybe Yang's name really is Yang Rose, but she goes by Yang Long in order to honor her father.
