I’m inclined to say that ^ but I’m also wary that then benches in particular have something else to berate the officials with after the review / decision, when they disagree with interpretation. I know rugby do it, so it can work – you just need the culture to change enough in football that they accept that some decisions aren’t necessarily black or white. But that’s poss even more the case in football than rugby – for example contact is almost never an issue in rugby, it’s allowed at almost any power and intent – no ‘it wasn’t enough to knock a player over, they’ve gone down too easy’ type judgement in rugby, it’s matters of fact mainly like was it below chest level, were they in the air, did they get tipped over horizontal, etc.
The main purpose of the audio update was i think to explain to people in the stadiums but the hand signals do it anyway, in my mind.
“After review” (we know, we saw you looking at the screen) “the decision is yellow card cancelled” (we know, you’re doing the crossed arms wave) “and the decision is red card” (we know, you’re now waving a red card)
