No, I can't, although I don't think it's necessary (see below). It would immediately convey some of the abuse from the players, but that's not a huge problem. It may be that it's a FIFA rule - I don't know if it's done in other countries, but it certainly isn't done in major tournaments.
Football is intransigent, and "how things are done" is difficult to fix. It took years before cricket was satisfied with their own system, and even a few years ago rugby still had problems with making things understood; I think there is a perception of how long each other sport got their act together. It's a work in progress.
Maguire's is as impossible to answer as the Pickford one last week - there shouldn't be a grey area on either. These should absolutely be explained afterwards by PGMOL, just as the midweek last season where there were 3 in an evening that PGMOL commented on were wrong - that would do without needing the replay of conversation.
