I have lost you on this. Are you sayin that if the kill switch is on the ground side a running car can not be stopped by flipping the switch? Please explain so the simple minded can understand.
Yes, an alternator back feeds enough to keep the motor running. Want to try it just go out start the car and pull off the battery cable, it will continue to run.
To stop a motor with an alternator you also need to break the feed from the alternator

Back when we were kids hang out with our first cars inevitably someone had a dead battery and none of us had jumper cables. Easy pull out your dead battery put in your buddys good one, start your car, pull the cables off, your car continues to run, give the battery back to your buddy, put your battery back in and hopefully when you hook it up it starts charging
