It's just anime only addition, possibly created as a prelude of Yamato's IT dream (also exclusive to the anime). In the manga, when Zetsu began to unwrap from Yamato, the Rinnegan can be seen in the latter's eye, which means he was already caught in IT. So Tobi-Zetsu doesn't protect from IT the person inside it, unlike Black Zetsu, who actually shielded Obito from its influence.
