I have my very own theory on how it works. Basically, Asura and Indra work sort of like 3rd parent to an incarnate, chakra wise. In short, Madara's chakra is part his father's, part his mother's and part Indra's. Likewise, Naruto's chakra is part Kushina's, part Minato's and part Asura's.

That's why Naruto-Hashirama, Sasuke-Madara have different chakra signatures. It also explains why Naruto seemingly inherited much less of Asura's power than Hashirama, parts of Minato and Kushina's chakras simply overwrote most of Asura's, meaning Naruto inherited less traits and power from Asura than his parents, while Hashirama seemingly inherited more.
