Yeah, uniques tend to be "stickier" than most demons, because they have a higher chance to be picked to spawn than most demon groups on a floor's table, and of course, once they spawn once, they never can again. But if they happen to get missed, it's theoretically possible for them to spawn on any higher floor, though after +2 the odds become rather remote.
