In either instance, it sounds like it will play out much like the first iteration of this mode from Kane and Lynch: Dead Men. Team with the most money wins and gets to split it evenly. What is interesting though, is I get the impression that during this go 'round, players who are back stabbed automatically hop to the AI cop side of things and get to hunt down those that turned on them in the first place. Nice little twist as I am sure that player will know how best to hunt your ass down after playing on your side and seeing your tactics first hand.
