It'd be hard for him not to die - the platfrom was shot with multiple missles, he didn't have much time, and he was wounded. If he wasn't kileld by the missiles, he could've easily been killed due to loss of blood - how would he get to shore?
There was the boat that was supposed to take them to the submarine. Chang gave Jack's dad the circuit board* and told him to get to the boat. That's what he was trying to do when the nephew shot him. It seemed very convenient.
My guess is that the circuit board is going to come into play next season.
*If tonight hadn't been the last night, I would have thought it was a fake and that Chang had the real one (he might still have it, anyway).
