He said that he had given Asura all of the power before prior to stating that this time he had given Naruto and Sasuke the same amount of power. There's no way he could have been talking about Ninshu since he didn't give Naruto and Sasuke anything like that, he just gave them both his chakra. So he must have given Asura whatever he had left on his deathbed.
