Why wouldn't you adjust his back to be facing you where you could accurately strike? Instead he does a reach-around strike which would be less accurate and would reduce the effectiveness and efficiency of said "fix". It's things like this where injuries probably stem from a person who is "trained to punch you in the lower back", considering this person doesn't have doctorate or nearly the extensive training to use physical abuse to fix someones back.
