During the Naruto vs Pain fight (before Edo Tensei), he has 6 bodies that he controls via Chakra and each body has the power of one path.
When Naruto kills anyone of them, it's stated that he loses usage to that particular power of path until he has another body for that.
My doubt is that since its just bodies controlled by chakra, why doesn't he use the remaining pain to use all the paths?
For example, if the summoning path dies, Why can't he use that path through the Yahiko pain or some other pain?
