Did anyone notice the sort of.... glass edges around the video that only fade away when the guy finds the leaf/ascends? They reminded me of the glass box thing the guy puts his head in at 5:45, if you were to look at it from directly above.
Also, I'm not sure what happens when he puts his head in it, but if the above is true, maybe he witnesses something similar to what we are when watching the video.
i have no idea, but that's a neat speculation. maybe a literal way of saying "think outside the box?" And one will only be "free of the box" during/after transfiguration or something.
