That's the most annoying inconsistency for me. I think that could be a patch to the wing applied after they managed to pull out the cloth from the spar (if you look at the blog a bit, there are some posts showing that issue). I think the shitty cut around 1:20ish could be them looking down during a screwed launch attempt, and splicing back in after adding the patch. You'll notice in the following video the patch is there from the start.

There is a Dutch news clipping from about a week after video 13 that shows the dude without the patch, which is puzzling. Again, easily explained as using an old photo from before 13, but still.
