To be fair, Condit isn't really planted properly for any of those techniques because he's getting ready to run away if Nick comes back at him.
But if he had been planted, he wouldn't have been ABLE to get away fast enough and he would have been getting hit back, which round one taught him, he couldn't afford to do.
He clearly had his feet set in both of the exchanges above, and he wasn't really losing round 1 either. Round 2 is the only one in which Diaz clearly got the better of Condit in the stand up. And he didn't really do any damage in that one either.
