Did you count him sealing Amaterasu in Sasuke's eye at the end too?? Tsukuyomi was used less than Amaterasu, but the difference isn't so huge. I think Itachi could get maybe 1 less usage of it because it takes that much more chakra to use.. thats why I think it was more plausible and reasonable to seal Amaterasu in Sasuke's eye instead as he really only had enough left for Amaterasu.
