You all are misunderstanding... A transmigrant dies, then the chakra gets reborn into another body afterwards, BUT it was never stated that the previous transmigrant loses that said chakra, it only gets placed again in another body. Hashirama and Madara never lost theirs. So that is why Sasuke gained the Rinnegan and Naruto didn't, because Sasuke got Asura's chakra from Hashirama, via Hashi himself and Kabuto basically replacing his damaged personnel with Hashirama's cells to heal and come back from the brink of death. Don't be surprised when Sasuke awakens Wood Release.
