I like it because I tend to believe that rumpled, beat-up-looking flies are attractive to fish.
Partly due to things I have read here and there, and because of Paul Schullery’s chapter, Rag Tag and Rumpled - The Mystery of the Ratty Fly, in his book Fly-Fishing Secrets of the Ancients.
You can read most of it on the following websites. However, in the book there are more pictures than shown in these two sites.

Indeed, Mr. Schullery’s article shows a picture of flies from 1789 that looks a lot like the flies Alejandro Gómez shows in the video.
I also found his history of silk worm gut interesting. When looking at old Japanese webpages about fishing I sometimes run across the word Gut ( ガット, gatto) or Silk Gut ( シルク・ガット, Shiruku Gatto) in the text. It often seems to be a name that originate from the British. But sometimes just used as a generic name for fishing line.
In fact there is a Japanese book, 英国のフライフィッシング史, UK/British Fly Fishing History, which writes about it.

Scroll up and check out the flies, on the page following the front cover.
The following document, The Story of Silk and Silkworm Gut, adds a bit more about how it was made, what countries had success making it and which did not. I think it is not the same document he referenced in the video, though perhaps it is, just a different chapter, as this document focuses on it’s use in surgery. But the process of making it is the same. I think. Kind of amazing that a single silk line could be made 2,400 feet in length, and very interesting history that at one time Silk was a national secret of China, its’ production only by royal hands, where it stayed until a Chinese princess married an Indian prince, and she smuggled some eggs into India and taught them how it was made. Later two Persian monks smuggled eggs from China concealed in a cane to Constantinople. Which for 1,200 years provided Europe with silk. And Murcia, Spain, remains a capitol of silk production. Or at least it was when this document was written.

The W.C. Stewart book, The Practical Angler is available on Amazon, pricey for print copies, but also available on Kindle. Eighth edition of this 1857 book.
“The trout within you wimplin’ burn,
Glides swift, a silver dart;
And safe beneath the shady thorn
Defies the angler’s art.”
His tying step of wrapping the Starling feather round the tying thread reminded me of how Takekabu-san, after tying on the end of the feather to the hook shank, then placed a half-hitch of thread over the free end of the feather before winding it onto the hook shank.
Anyway, I have a Starling skin, I will have to give this method of tying a fly a try.
