In chapter 519, Rangiku scolds him for not behaving properly and that although he was a branch, he risked affecting the main house too. It's almost impossible that the head of the clan belong to the branch house, although I wouldn't be surprised at all if thing turned out differently. The misunderstanding might stem from the scanlations not being that clear, because they make it appear just like you say, member of the branch house and head of the clan at the same time.
