Very likely the case. *nods* Gene kind of has to forget in order to sustain himself in "his" world, in order to do what he does. Eventually, the cycle will be repeated again, and again, and again, until it can't be anymore. It's likely some sort of scenario would, eventually, be concocted in order to explain what happened to Alex, Ray, Chris, and Shaz, which -- at some point -- someone would have to investigate, in order to restart the cycle.

The longer you are there, the more you forget.
There may have been an element of truth in what Thordy said in the interrogation.
"This world is different, you forget things"
Gene, ultimately, forgot he was dead. So did Ray, Chris, and Shaz. I imagine Sam forgot for a while, too, but ended up remembering somehow. Maybe even Annie. In S3, Alex virtually forgot about Molly, forgot about wanting to go home
to her. It wasn't until the farmhouse that she remembered.
