I'm sure amongst all those chaotic lines of communication between officials, there is a bit where the actual VAR official gives his reason for his decision. That's the only bit that matters.Part of reasoning is what IFAB allows and doesn't allow.

It's not helped this season when it's almost been made to look like they've created a relegation battle that should never have existed.
