The whole story sounds fishy. The enemy flag won't go up if your team is there. You won't get TKs for killing the enemy. Even if, and this is a looooooong shot, all three of those guys had the red name bug, then the MEC flag would have been rising. I think you just weren't paying attention or were confused.

I would've punished you for that. Everyone here's probably been TKed a hundred times when they were seconds away from capping a flag from some moron who's too lazy to see if anyone's there first.
