I think this is exactly what the IFAB asked for when it made its change. The referee is 100% in the right, based on the new Law. In fact, I'd argue he is obligated to do this based on the text. But no one else asked for it, so you're not going to see this in major competitions. Hopefully that means IFAB will realize the error of its way and this will ultimately be taken off the books. Otherwise you're just going to see wild discrepancies in application.
