@Pregaiden, I think you are the one who should rewatch. The events go like this:
 * Madara gets Rinnegan in old age
 * unspecified time later, presumably years for all we know, find very young child Nagato and puts his Rinnegan into him
 * years later Madara finds Obito, Madara dies
 * Obito goes after Nagato
 * Nagato summons Gedo Mazo
