Yep, but he said that he pushed the clutch in with his right foot and started the car. So he wasnt' completely inside the car, just reached over to the key and started it. Then he proceeds to leave the car and withdrawed his right foot (and it happened that it's in gear).
Seriously, the dealer isn't gonna do squat since you're the one who started the engine (last touch). I'm surprised that he didn't ask you to pay for damage for the Altima you hit. And like you said in the very first line, it's your fault. So why would they pay for that?
