Judging by the exploded view on their site, I don't think they do. That might be a simplified view, though.I think the Detroit tru-trak has clutches. It will drive with one wheel in the air unlike the torsen.
If it is able to drive with one wheel in the air, it's due to preload. I ran a Quaife (a different manufacturer with a similar approach) a long time ago that had a small stack of belleville washers which provided the ability to change preload. This would provide some amount of drive with 1 wheel in the air.
Generally speaking, if you've got a rear tire in the air for any significant portion of time on a rear wheel drive car, you've got bigger problems than just the diff.
