Yeah but in cricket your hear the whole discussion (which is great - Rugby is very similar). All they are doing here is communicating the final decision, so Mr Magoo will still be in front of the screen watching multiple replays and you won’t know why.
It’s a start, but at this stage it’s only the final decision, none of the discussion or reason why the ref has been sent the review it on screen. Hopefully that will come in due course.
