So there aren’t two realities, one where they’re still debating and one where they aren’t. In both realities the debate has concluded, it’s just our observation of the event takes place at different reference times. Yeah, they're making the mistake of assuming a minute is a minute. It's closer to the difference in angular motion vs linear motion. If you are closer to the center, you move very little linearly. If you are closer to the outer edge, you move very little angularly. Now you look at the linear distance as time passed for the object and the angular distance as the amount of "space-time" an object has gone. The amount of "space-time" is constant. It's a bit of a wonky model, but it's probably the simplest one that encapsulates the concept. So just because they spent 3 days debating, you spent 5 days watching, and Bob only spent 1 day watching; that doesn't mean Bob is 2 days ahead of Andromeda and 4 days ahead of you. Since we are all also traveling through space at different speeds, we've all traveled the same amount of space-time, so we're all seeing the same things. As for our perception, that more depends on our relative positions from each other rather than speed. Because nothing is faster than light, we can never experience an event before we see it.
