I know that, just sayin it's a weird mechanic to pump them full of lead and their still breathingf you dont head shot or maim them, then when they first go down they are still alive, if you want them dead you then have to finish them off - but they never get back up and are for all intents and purposes dead regardless of whether you finish them off or not. It only matters in missions like the cyberpsycho ones where the main goal is to incapacitate rather than kill.
