Yes, but like the handball in scoring they are also changing rules to suit VAR (making them black and white) not the good of the game.So in other words they use it (or not) when they see fit and can manipulate a result, or decide to slow down or quicken up the frames and create some line to suit a decision, like the Son disallowed goal against Leicester.
They can explain away anything as it's all horses for courses.
Expect more rule changes that suit VAR but are detrimental to the game in the future. I can't see them admitting it's shit but will keep trying to improve it, but make the game worse.
