That actually works quite well if you step-switch stances and counter with a cross/overhand immediately after the interception. At least it will the first time no problem. There's a bit of choreography to it, but its such an unexpected motion that it throws the opponent off. However its advised to snap the intercepting arm up to a deflective block for any kind of counter-counter(such as a cross) to the head. If done right its a rather sick and effective movement.
