I think the idea is, "I only have a sniper rifle! I have no close combat ability!  I need to get out of here!" Honestly, I find Nemeses kind of funny -- their fast, chittery vocalization and the way they skittishly run from cover to cover or quickly pop out to fire give me the impression that they're terrified half out of their wits, and also probably hopped up on who knows what kinds of stimulants. From that point of view, I see the AI behavior as a form of characterization -- yes, maybe it would make sense for that Nemesis to try to shoot the player at point-blank, but she's running away instead because she's terrified.

If we're talking about AI behaviors that don't make sense, I'd actually single out the Nemesis' malicious sister, the Phantom. They have a tendency to stand out in the open and let themselves get shot a bit more often than I find reasonable. They also don't make as much use of their cloak as would make sense to me. Not that I'm complaining -- they're hard enough to deal with already! -- but I do find their behavior a little odd.
