Btw way the translation
How will the ref behave when the player is on offside position at the moment of the pass (shot) of his team mate , but he doesn't get the ball directly , but as a result of a deviation of a player , the post , the corner flag , a ref assistent ?
In this case the ref may award it as an offside in the case when the player has an advantage because of his position .
What i suppose he is trying to say is that , if he was offside at the moment of the pass than even through the ball touched the post (which with new rules is like a player of the oposition team touching the ball , making everyone of your team onside no matter where they are if i am not mistaken) and he was onside , the ref may award it as offside if he has an advantage from his position
The key point here is the part in black , because he was not offside at the moment of the pass , asamoah clearly kept him onside
