IMO saying they CAN'T happen from either end is not reasonable. To me it makes more sense that flame can get past an ill-fitting cap or an empty cone than past a ball that cut a ring upon seating. But I wouldn't bet my life on either and I'm confident that chainfires have happened from either end. Thankfully I haven't experienced one yet.
I've tried and tried to get a chain from the nipple end and can't do it.
