A good video, but I would only take it literally for the closest peg to the nut (E). For me, too many windings away from the tuning handle for the A, because the D will rub against it (and break some silk fibers over time when tuning) as he has done it and there is enough room on the other side to get one and a half windings more there. The angle at the nut is mostly influenced by the distance to the pegs, so more important to the winding structure of the closer pegs, basically no problem for the more distant pegs of the A and D.
If you don‘t cut strings they are better to sell later. Cut strings can get a bit too short for bigger instruments.
