I think the implicit assumption is that the ghosts always relate to the “real” decision. You can of course imagine what people (=their ghosts) would do in all kinds of strange situations but as long as you don’t act on it it doesn’t matter. I realized this when I imagined myself being a ghost right now (or rather at the section where eva suggested that), i.e., I generalized to situations where nobody is doing the simulating.
