It's not about being recognized, it's about when you are asked to be patted down, having the courage to lie "I can't raise my arms over my head", knowing the risk of being caught is at worst not making this flight. For a foreigner it might be getting banned permanently from the country. Same concept as self censorship. You do what you're told and then you go enjoy your vacation.

You only get a pat down if you trigger additional screening or opt out. Not being able to raise my arms is NOT opting out. Therefore, no pat down.
