I was taught a similar technique by an old electrician I worked for out of high school.
That old dude screamed at me "Why do you insist on fucking up my power cords so bad!!!" Which left me speechless as I knew no other way other than wrapping them around my arm like the teenybopper I was.
Then he showed me the light and lookit that, the next day the cords were much easier to handle and the "New" way I learned was even faster.
Pretty much similar to what is in the vid, but I was taught to go a full two arms length, then join the loops. Spread your arms fully while holding the cable, then bring them together making about a 3' long loop.
Yeah, you can adjust how long each wrap is to determine the final loop size. I usually pull like 4' to end up with a 2' loop because of where I hang them.
But the main thing I like is using your thumb direction to place each wrap the right direction.
