^^ I'd say it's still possible that he's a TSB, he was able to use any techniques of the bodies that he attached himself to without any trouble, him being able to be cut in half could be explained as him being unable to use yin-yang or not bothering to prevent damage since he can just reform himself. Also Naruto's Sage upgrade allowed him to resist Zetsu's chakra absorbing while Sasuke was helpless and later allowed him to throw Zetsu into the moon without Zetsu becoming goo and escaping.
