@Flatzone no, Sasuke doesn't get Itachi's MS abilities from EMS. Because of the sole fact that he doesn't have Tsukuyomi.

So no, Sasuke wouldn't end up with Amaterasu automatically, and your argument falls apart there.

EMS is different than other dojutsu transfers. The person gets their close relative's eyes, but since they themselves have the MS, their own power is what comes through it. They get a boost in terms of no more strain, but they don't get their techs with it.

Besides Tsukuyomi, Sasuke also doesn't have Totsuka Blade or Yata Mirror. So no, Koto can't be coded to Itachi's Amaterasu because Itachi doesn't know what Sasuke would awaken.

And there's also the fact that there's no reason to add an unnecessary two-step conditional system to Koto when Itachi just wants Sasuke to not attack Naruto/Konoha.
