Oh, that was different. I was responding to this comment, which was clearly a criticism:
I meant we do it that way because that is the technique. We intercept the Yokomen while it is still winding up.
There shouldn't be a clash if the attack is still winding up! Banging means you are hitting him as he is hitting you. That's karate. If you hit him between the time he DECIDES to attack, and the time his arm has begun its strike, then you are actually hitting him much harder.
