They gave Asura the rasengan orbit and WR, they gave Indra Sasuke's MS, amaterasu, that variation of chidori, and his older self looked identical to Madara. I'm thinking it's less of an effort to make Indra and Asura look similar to Naruto and Sasuke and more like "okay, the manga's ahead enough - let's wrap this shit up quickly and get on with the canon". There was even a shot of Full Body Susanoo and Asura's Wood Golem approaching one another that looked a helluva lot like the one we saw in Hashirama vs. Madara fight.

Low effort, as I said.
