Me thinks Re-Ron feels that the Demon Kristen is the same one, just faking John out, or something equally stupid, since the entire premise is ridiculous. Gimmicks. Perhaps at some point he may explain what or why he thought this would work, but doubt it. While some fans have been vocal in wanting Eileen as Kristen, maybe he figured he'd throw them a bone. (just know the actress has no interest in returning for a lengthy stay as Kristen, & has indicated that several times)
