Not really. As I just posted, if any part of your body with which you can score is ahead of the defenders, you are offside. Looking at that replay, his backside (a part of his body with which it is legal to score) was ahead of the defenders foot. It was off side.
I agree with your interpretation of the law, but the replay they just showed clearly had his backside bang on in line with muntari's foot - they even drew the line!
