To live again in a new body — continuity by rebirth; what a good pattern does in its next home.
Re- (Latin, again) attached to incarnate, from Latin incarnare (to make flesh): in- (into) + caro/carnis (flesh); to reincarnate is to be made flesh again, continuity carried through a new body rather than the same one kept.
To live again in a new body — continuity by rebirth rather than by preservation. The root's flesh made anew is exactly what a good pattern does when it finds its next home.
