[Blade Runner 2049] Why did K even consider the possibility that he was the unique replicant in question if the birthdate was 2019 and Nexus 9's didn't even start being grown until 2036?

If he was the unique replicant, then he wouldn't have been a Nexus 9, just "undercover" as a Nexus 9 to stay hidden from the authorities. As a nexus 9, he believed the memories to be implants. But upon learning that he could be the unique replicant, he believed the implanted memories to be real.
