This is the way they did it n replay's original incantation. After a year or two it was canned. I was at a game where the sky ref gave a team a TD which was wroooong. The ref even admitted it later.
Through the first 9 weeks, PI was changed 9 times due to review.

That said, I'm glad it's gone. I'm also a big proponent of getting rid of replay altogether. Replay review adds about 15 minutes to the game and the calls are still screwed up. What's the point?
