I don't even understand what that's supposed to mean. They warned him, then when he didn't abide their warning, suddenly they have to talk to the umpires, make sure he stays in his crease, write a notarised letter to his attorney, the ECB & the Queen, lobby for a governmental intervention, start a social medi....wha? Then do a pretend appeal. He's an international cricketer, for crissake he's responsible for staying in his own darn crease.
Also, I don't get the nonchalance behind him being just a couple inches over, those couple of inches could mean the difference between being in or out if the stumps are hit on the other end. If the umpire spots a fielder a couple inches before the line when walking in, then he should no-ball the bowler (you know, like they occasionally do anyway). An inch over is as good as a foot over.
