They are supposed to remain dead once they die after all, and it's the only explanation I can think of with characters not remembering things after death, and stating they will talk with other dead people once they return to the afterlife.

Zabuza specifically said not a second passed, and only Obito and Hagoromo seem to have afterlives. Minato assumes he will see Kushina but that's because time actually passes in the Reaper's stomach.
