No, he didn't outsmart him.
Itachi's only goal regarding that incident with the Totsuka sealing was to remove the curse mark from Sasuke so that he would no longer be in harm's way.
This succeeded. Orochimaru has no chance of taking over Sasuke's body now.
Sadly, this thread was incorrect and has no point.
Orochimaru can come back as long as someone is around to reverse the seal on one of his subordinates who still has a cm. Sasuke let out a hideout full of CM users, so Oro's good there. However, if he dies or is sealed away again, he won't be able to have a clone version come back that retains his consciousness this time around. Sasuke wouldn't be willing to bring him back (he only brought him out of necessity) and Kabuto is leaving Oro. Lol
Uh... That's not what it is at all...
He was absorbed by Sasuke, then he escaped. Same Orochimaru. He was pierced by Totsuka, but escaped that too. As a small snake he was burned by the flames of Amaterasu. But he remained alive in Kabuto and his Curse Marks, he held a consciousness within them. So Orochimaru is still the one and only...
Six Paths basically said the same thing. The body that was within Sasuke's CM was absorbed into Totsuka. It's still there. However, Orochimaru can maintain consciousness through anyone who still has a CM, hence why Anko was used and all Sasuke had to do was reverse her seal.
It's Orochimaru in a way, since this version still has the same knowledge that the one sealed in Totsuka had. But, it's not physically the same exact one that was sealed away.
