I hate the rule but I do think it will open up the game and it will probably be the most frustrating rule change yet.In theory yes, but I can see it turning into a shitshow
There are other ways to open up the game, which won't lead to further inconsistencies in interpretation
Edit. Just imagine if Castagna lead you to the ball and marks just outside the 50 So you take the mark knowing he can’t score, (he would also be able to kick from a distance he could score from with no one on the mark) just to have Dusty stroll past you without you being able to do nothing to block his run and have a fairly simple shot for him on goal. Would be infuriating to watch.
