Having experienced slight feelings of melange/detachment following novels, video games, and movies in the past, and having experienced what this article is describing: it's not quite the same feeling.

With movies/novels/etc., I've always experienced what you're describing as something similar to a feeling of loss--the world you experienced or the story you were involved in or the characters you cared about will no longer be there as a new experience, no longer have new experiences as characters, etc. That 'world' is gone.

With VR, even if I don't really miss the experience, I've experienced what I'd describe as a "readjustment" phase of between 10 minutes and a couple hours (depending on length of experience and how recently I'd been in VR) where the real world feels disconnected/less real. It's a much more intense and visceral feeling, and doesn't have the same undertone of 'loss' that movies/novels have. It isn't a "Man, I'm not actually a space pilot in the year 3000" feeling, or a "I'll never be able to experience that world again" feeling, it's more of a visceral disassociation from the real world, as though my senses don't feel like they can quite trust the inputs they're receiving anymore.
