Why do you always have to think everyone is arguing with you Ian !
There is only an issue here for someone who massively over analyses everything.
He was fouled inside the box. Nothing else matters.
Even the ref wouldn;t be so damned anal as to try and work out if the first foul had sufficient force to knock him over without the second foul. From where I was it was nothing like the Bellamy incident which happened because from the angle the ref was at it looked like the defender had hold of Bellamy all the way into the box.
