What you might not realize is that they aren't going after you, they're going after a noise. If you get away after a suspicion is raised you can flank enemies while they go ballistic on where they think an intruder MIGHT have been. They operate on sound a lot of the time. If they hear a helmet being shot or an enemy shooting at someone, that will trigger a suspicion alert. Reflex mode is all about preventing that warning cry from going out.
The enemy's vision, for the most part, works on movement. When they're shining the flashlight they're seeing if something moves. It's actually very intricate AI and when you really understand the rules it operates on you can perform some amazing feats.
But soldiers yells most of the time during reflex mode but that doesn't trigger an alert. And these guys aren't freaking T-Rexes. Russians soldiers could still see Snake in Mgs3 even when wearing the right camouflage and hiding the in the grass.
