^ Hagoromo also said he will share his chakra between Naruto and Sasuke. While Hagoromo said one needs his complete chakra to awake Rineegan, I don't think he said that's only thing that will be awaken. Maybe Hagoromo's complete chakra affects differently with Asura and Indra's reincarnations: with Indra's, they would awake Rinnegan while with Asura's they would awake Six Paths Senjutsu.
