Yeah, that's true. But I think it's pointless to divide Hag's chakra into Indra/Asura halves since technically it's a single entity and not just a mix of Indra/Asura chakra that can be divided into the two single components back again.

I've got an idea to explain it after I remembered Orochimaru's words about techniques, though I'll just use his scheme and not the idea. Let's say that Hag's Chakra is green. By his sons, it regressed into Indra's blue and Asura's yellow Chakra. Only by mixing blue and yellow, green'' could be recreated once again. But Hagoromo himself didn't just have blue and yellow to constantly mix them into green, he had green from the very beginning, and if he grants someone the halves of it, these would be two halves of green and not one blue half and one yellow'' half.
