It would seem to me that standing on the goal line wouldn't necessarily mean that you had broken those guidelines. So potentially it could happen.
Assuming you genuinely didn't prevent the keeper or another player from being able to play the ball, then is it really that much of an advantage to be on the line? I would imagine that the risk of just getting in the way and therefore 'interfering with an opposition player' would outweigh any benefit you might get.
Would be interesting to see how a referee did interpret that situation though.
I'm not suggesting that the guidelines are right and cover every situation in a way which makes sense. Just that in this instance the referee appears to have applied the guidelines and it's hard to see how he could have given Rooney as offside in that instance, without just ignoring the guidelines that he's meant to follow.
