over on reddit (ahahahaha, I went for the extra drama) the argument being that if the time has to be pieced together from videos and there is no official doing the actual timekeeping then clearly the time is not important to FIG and the rule is only a guideline. If it were important (like the length of a period in basektball), there wouldn't be all this argument and counterargument, it would just be known. Which is an interesting take. Since they do have someone as a timekeeper for the duration of the routine (well, it was a person with a bell at US Trials, I don't know about the Os, maybe it is computer generated there), if the review time was equally important they would have someone keeping the time.
