Ah, that explains it. It does look way more artsy than the shots they ended up using in the film for some reason. I think it would slot in perfectly in place of the Kylo shot readying himself as Vader approaches him that I had to remove for continuity.
One thing worth considering about the rapid-fire visions in TROS is that they include footage from random parts of the previous movies, thus necessitating such a film style. What we have here is entirely new footage that is already arranged in a narrative format, so I really don’t think the same technique is necessary.
