this would have completely missed.
We can't eliminate the possibility of doing this - if you can't do this, you can't 180 after parrying and riposte into a guy behind you, etc - the combat would be broken. Instead, we make things like this not effective. This move in the clip is not effective, all you need to do is back up. People do these things to flex, not because they're actually useful.
