Physical Sleep protection after missed ko trap?

Is this really necessary - or maybe a bug I hope? Opponent trips trap, fails to inhale noxious gas. ok, i'll garrotte He is guarding his neck too closely. I haven't been able to tell if you can still be ko'd by a trap if you have the physical sleep protection timer - but you used to be able to get ko'd by a trap, then potentially get trap ko'd again (if trapper was lucky enough), or, at least, miss a ko trap, then get hit by the other one. (so the trapper can stack his odds with more traps/time/planning).
