Hm the back to me can be, because there is a mechanic for the AI to mainly focus head shots and when I'm so close it seems that my vital spot is out of range.
I watched the video again today and there is a second aspect.
When the bandit swapped his missile weapon to his melee weapon and I was running at him again, he hasn't had any push back. So it seems that the stance for throwing weapons causing this weird push back effect.
Also as I mentioned this problem I've played a character focused on throwing so maybe the problem can be found there.
