No, it becomes a different bush because most of the organisms on the bush are
in so many ways different from most of the organisms in the parent bush.

By the way, tell the above to crown-group cladists sometime. They frequently
name major clades on the basis of their extant surviving groups. E.g.,
Archosauria = last common ancestor of extant Crocodylia and Aves + all its
descendants.
