Kayaba probably had the scenario planned or when people reached the final floor that he would be able to interact with the party that killed him per se so it likely sent related people even killed ones by him to a halt and when they cleared the game Kayaba could give his monologue of megalomania (he wanted to create a realized world and exert his dominance(world) over people by force, if that isn't megalomania nothing is)
