As I mentioned in the video, you don't need to have a Cintiq for this workflow. The real advantage of the touch screen is to manipulate two different screens with to different imputs (pen and touch).
You can totally use the Express Keys or even a button on your pen to map the 'Screen toggle' which essentially swtiches monitors for the table imput area and that way you can use the technique. However, based on my experience, splitting the two imput types to two different monitors, makes it very intuitive... This process is purely about building that muscle memory so you can work faster.
Here is a quick list of the Wacom devices that have the touch capability (inlucing the Cintiq of course):
All sizes of the Intuos Pro have it:
The Mobile studio Pro too obviously:
And the Cintiqs PRO (the ones that are not 'Pro' have not touch imput):
The Wacome One is great BUT is not touch screen
Hopefully these list helps. Always double check there are some odd varaitions where there migth not be touch.
Another realy cool thing you can do with the touch options in your Wacom is to use the Wacom drivers to setup custom actions or 'shortcuts' for specific gestures. For instance one of the most frustrating things for me is to have to put my keyboard away when I'm working on the 'standing' mode of my desk (how I was working on the video tutorial), so I can map the 'swipe down' gesture with 5 fingers to run anything I want like the windows 'On-Screen Keyboard'
