Or perhaps they still retain consciousness and their memories when they go to the Pure Land, but upon being reincarnated they lose their memories? 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.
