Unfortunately, they followed the NFL's replay procedure and first make a call, most of the time. On a few occasions, I have seen the ball go out of bounds with the ref calling a 'jump ball', knowing that he was going to review it anyway. I think this is what you are talking about.
In any sport, I always hated the idea of having to stay with the original call if the replay was not clearly 'overturnable'. I suppose I understand it if it is truly inconclusive (extremely rare), but too many times in the NFL, a play was not overturned that likely would have gone the other way if there was never a definitive call in the first place.
