Won't comment on the video because I've not watched it yet.
Normal daisy soloing is done without a rope. Not that it's a very normal thing to do!
You would be set up with two daisy chains attached to your harness. They can be old style daisy's, adjustable webbing daisy's, adjustable rope daisy's (e.g. petzl evolve adjust), just a sling. Basically anything that can act like a tether from you to a piece of gear.
Then as you climb you clip a daisy to a bit of gear as you pass it. Having two daisies means if there's enough gear options you can always be attached to something. E.g. on an ice pitch you could place a high screw, clip a daisy to it, climb up until that screw is about knee level (or however far down you can reach to unclip), place another high screw, clip the other daisy to it, unclip the first daisy, climb up, repeat. Tbh it sounds like it would be a massive faff on ice, placing (and possibly removing) all the screws. It can be very quick and safe on a bolt ladder.
When you climb above the piece you're daisies to it's the same as going above an anchor when attached to it with a sling, which is beaten into people as being a bad thing to do, so it's obviously not ideal safety wise. It is definitely safer using a daisy made from dynamic rope than something static like dyneema webbing.
As I said I've not watched the video , but there are various ways to use a full length rope in a similar way as you would a pair of daisies.
This video shows a rope access person doing what they call vertical aid climbing (they also use cowstail instead of daisy, essentially the same thing). https://youtu.be/hzt-qsjBoRY?si=q39430LKVWoPjMF2 (search Access Techniques Vertical Aid Climbing and drop tests if you don't want to click a random link) It's basically the same thing as daisy soloing except they use three daisies instead of two so they can always be attached to two points.
