I've tried this a few times, and am impressed with the results. I have no idea how and why it works so well, and that of course bothers me a lot - but then you're not supposed to look a gift horse in the mouth

Hop creep has really been a great nuisance for me, and has more or less put me off dry hopping. So when I read about this for the first time, I thought I saw a way round that problem.
The first time I tried it, I pulled the wort at too low temperature, during the cooling after the boil. That didn't take care of the unwanted enzymes. So now I take the wort after 20 minutes of boiling, filling it on top of the hops in a 2 litres (2 quarts) e-flask, cap it and just let it sit under a blanket till through cooling. The I put it in cold water, and it cools while I'm letting the trub precipitate in the kettle. I add the whole thing, hops and all. (I fill a bottle with wort before filling the fermenter, and use it to rinse out the e-flask. Very useful.)
Last I did was a NEIPA, and it really has turned out well. I see no reason to dry hop in addition to the dip hop. (NEIPA is not my cup of tea, by the way, but The Light of My Life loves it, so ... . )
Seems there are many ways to do this, though. I guess some methods will prove themselves better than others after a while, but for now I'm happy doing it like this.
