I did read recently that animal (and human) reactions are not fight-or-flight, but fight-or-flight-or-freeze. I've never run into the variant of flight-or-fight-with-a-shotgun-or-shove-things-up-your-own-ass.
About a minute before you mentioned the motion streaks on the 2nd game, I had also noticed the streaks on the fencer are all fucked up. The silhouette looks like epee, but there's no time he should be swinging straight down like the motion streak is implying. You might do that with saber, but then there would be a different silhouette for the guard. In either case, clearly messed up.
