Or conversely, Solution 9 is behind a vault door, but it's a Fallout situation and the multiple shots we see of the door aren't all the same one and the City of Gold is behind a separate instance.

Another small, random detail I noticed is that in the very quick clip of the S9-themed water dungeon, you can see what appears to be one of the shock trooper people fighting a creature/construct in the background.
I can definitely see this as being a misdirect. You never want to give too much away before release.
