I suspect the way this works is that Mobage is running an algorithm for each bridge where the cars are running like a score ticker on espn, and when a person makes their pull they get whatever is at the front of the ticker. I doubt they are distributing cards based on what is already in decks. I would bet however that the algorithm does not just alternate to ensure that people spend more money by making the bridges unpredictable. This is all just speculation, but that's what it looks like to me.
