Minor bloodlines Spoilers, Read post at own Risk
Bloodlines is only 6 years or so Before TFA, and aside from Leia not being able to contact Luke there’s nothing to indicate Ben has turned. And difficulty in sending a message isn’t quite evidence of him being turned. So if Rey was being trained by Luke, then the false memories would be to erase her return to Jakku, or otherwise replace the last seven or eight years of her life with false Memories of Jakku, as she’d be thirteen when Bloodlines takes place.
