Except White and Black Zetsus were alive independently of each other. You make it sounds like if BZ were just a tumor growing on WZ. They separated, both continued to live separately, WZ got killed and yet BZ is still alive despite that, meaning BZ wasn't created from the life of WZ nor are their lives linked.
