No, the article is right, "set distance" means that the eye focuses on a distance that is fixed, namely the distance to screens. It can have full stereoscopic 3D and still force the human eye to focus at a given distance. This is a big change from real life, where the eye is continuously changing the focus based on the depth of objects of interest.

Other, non-screen based technologies, such as DLP [1] would allow the rendered field of depth to adjust based on the eye's focus, allowing the scene to be more realistic, and reducing mental fatigue. I think there was a different company using someting like this. [2]

Yeah, I work on VR and know of alternatives to stereoscopic displays. I still maintain that the writer is wrong and doesn't understand what they're describing:

"On Oculus Rift and pretty much every other virtual and augmented reality experience, what the viewer sees is flat and floating in space at a set distance. What Magic Leap purports to do is make you think you’re seeing a real 3-D object on top of the real world."

Good stereoscopic 3D does not give a sensation of seeing something flat and floating in space at a set distance.
