Obito got to Sasuke first which is way Sasuke's in a mess. Obito explained the truth in a way that Itachi didn't really have a choice. But Itachi showed him it was really his choice

Of course, though it didn't feel like he understood that when he learned the truth from Itachi, since he still said he couldn't forgive the Hidden Leaf.
