All I really understood was it starts in the bottom right going up and changes direction whenever it reaches the end in a snake like pattern. I think from doing that but with every square being a hex/RGB pixel the amount of information that could be stored could be huge. The video also mentioned if you made a random pattern its likely it would mean nothing. Using some of the patterns that don't translate to anything and having them mean their own thing could add even more information. I might be getting ahead of myself but this could be useful for stuff like peertube storing videos using less storage and then decoding them. The main problem is I would need to find someone who knows how to make qr hexcode/hybrid a reality since I have no idea how I would go about it.
