I don't agree, while the zombies are capable of wielding weapons, they don't bother to block, demonstrating a lack of self-preservation.
Putting aside whether the zombies fleeing is realistic or not, I'm getting a gut feeling that it's not good for gameplay. The zombies run very fast, this can be frustrating as the only way to catch up with them is to trap them as the video demonstrates. This can remind the player of the lack of realism in the game.
"Why can't I damage the zombie in the leg first to slow him down if he flees?"
"Can a badly damaged zombie run that fast?"
