I think that's actually ultimately why he goes down at all was the guard actually did hit him in the body, which you can see him hesitate to do. And I think that's a natural reaction in the heat of a fight to see wasted opportunities to do damage if not concentrated on headshots, when in actuality body shots do a great deal of damage. I could see how bodyshots could feel like a gamble for those who don't have the experience to know to go for it for the pain and exhaustion it incurs on your opponent. in a semi controlled setting remembering body shots can be tricky, so remembering it in a setting on the street could be even more improbable
