The Author had Naruto say that, the purpose was to show that even a perfect Jinchuriki would be beaten by Tsukuyomi. Samehada's regeneration has only been shown to heal physical wounds so applying that healing to Tsukuyomi's after effect is speculative. It was said only Tsunade could heal that kind of damage and that means it has something to do with the knowledge and skill needed for it.
