Yes, Robertson can be clearly seen, when the ball in played into the box and there's the coming together, that he doesn't think anything untoward has happened (otherwise he'd have given a free kick straightaway) so he moves away slightly backwards and to the side to see what was going to develop and then when Hoillet gets cleaned out, has a flashback in his brain and says "Oh yes, on 2nd thoughts there's a foul on the wimp in green". It may well have been overruled in any case (don't know which GFA/Sky official was on VAR) though it wasn't any more of a foul than the septic player on McDonald's fuck-up. Neither were fouls.
