Yes and that means you managed to meet with everyone in the map.
You can go join the other instances in this case. Sadly we can't really force everyone to remain until everyone else is matched . Sometimes it can be because of a family emergency irl. Maybe something came up. VRchat crashing is suspect as well but in that case they can just re-join back in. Re-joining flushes your name clean again as well so you can re-match with everyone else again in that instance.
Though it's recommended to go to the other instance so you get matched with people you haven't met yet
