What are you talking about? It’s a nursery and DWN has been the major conduit for publicizing this method. .
If you’ve had success, let’s talk about it and maybe show us some pictures of your trees.
Also, please explain how 4 trees in a hole has an advantage over a single tree with 4 varieties.
What research?
I did that this spring in another thread. All my trees were shown. I have been swamped with work this spring and am finding it hard to reply to everything. Plus I’m currently in physical therapy. Which is taking a lot of time up.

I never liked that method and would not suggest doing it. I agree with you as my trees are multiple variety. Introducing root and light competition is not a good idea. Also lack of good air flow can invite problems. This seems more a marketing technique of DWN.
I ran across a nursery here with about a thousand trees that plants them at four feet. All apples, it’s an apple orchard for u puck.
I hope to get some pictures in the fall it’s closed to the public until ripe. I did take a photo from the road.
I too am no expert - still fumbling around, actually!
However . . . I definitely second @rooftop_orchard. And this is from painful painful experience!!!
Don’t be afraid to limit the number of your scaffolds and keep space between them, both vertically spacing them along the trunk - and horizontally spacing them. Trim back the ‘spindliness’ or you will get end-of-the-branch bearers and lots of sag. By trimming them back - they should thicken and strengthen and produce more fruiting buds, rather than just ‘greenery’.
Ouch. I had to learn the hard way! 
And I’m still trying to make up for tons of early training errors.
If you want little fruit trees… this to me makes alot of sense. Thanks to @Drew51 for suggesting the DWN videos.
