Yes, this one looks the best if you are constrained in what you have to work with. I actually read the compression methods in "Five Last Acts", and they made it look so easy... After I experimented, it turned out to be actually quite more complicated. I ended up with the same idea, that you want to press the arteries specifically with something. Otherwise, you may block just the veins and end with a headache, or even worse...
I'm quite disappointed by this book (Five Last Acts), it looks now very amateurish to me. Since most methods involve depriving the brain from oxygen, you must really take care about your setup, or you can end up even worse then you started...
What I like about this method is that there are less parts that can fail. It always stays fixed to you. It also works based on simple mechanics. Presenting drugs in your body is more difficult to predict, especially if you don't know their purity. IMO, these bags may be an issue, it's better if they are fixed to the band a bit better. You don't want them to get out of place. If it's made somehow from one piece, it would be really safer.
