I don't think this rule has even been exploited fully yet.
On Saturday Fritsch took a mark about 45m out and was standing at the end of his set shot routine from about 65m. Rivers called for it running past but when Fritsch handballed it to him, the ump called play on so the man on the mark was able to run towards Rivers who had to kick it from about 55m. Wasn't really the smartest play to call for it so far out.
To exploit this, once the ump has called "stand" the player taking the kick should be as close as possible to the mark and have players running past. This way Rivers should have been able to clear the man on the mark and kick from 40m.
Previously the man on the mark would have seen this and shifted sideways to cut off the run through. It may even cause a 50m penalty if the man on the mark goes too soon
