Why didn't he show it then? Just because he has the ability to absorb ninjutsu, doesn't automatically mean he had the rinnegan. Even this supposed absorption ability seems questionable or isn't as reliable as preta path/Momo's ability. Ofc, this could explain why sasuke wasn't using chidori katana but he still had other chances of using it. To make matters worse, we haven't even seen it in action either.
