I actually just finished up a study on ankylosing spondylitits so the next year of my my life will be devoted to giving lectures on the subject. There's a little crossover here..
Try doing those exercises sitting up, and then lay down on the floor and do them. You'll see a huge difference.
If you are doing cervical range of motion exercises, you need to eliminate gravity.
Try this experiment. Sit in your chair and see if you can touch your ear to your shoulder. You'll get about half way. Now, lay down on the floor and do the same movement. You should easily touch your ear to your shoulder.
This is why when I am assessing cervical ROM the patient has to be in a gravity neutral position. The same goes for range of motion exercises. Doing ROM exercises in sitting or standing are nor going to be beneficial.
I'm not quite sure what tinnitus has to do with this. that's an inner ear disorder with nothing to do with the cervical musculature. In fact, I'm pretty sure that this guy probably doesn't know what tinnitus is.
I also will stop short of pointing out all the physiological inaccuracies in this guys explanations since nothing he suggests is harmful.
A very common trend these days is the "release" of soft tissue. In fact there are many courses that will charge you a lot of money to do "soft tissue release". After you've dissected a human body and spent hours slicing through fascia with a scalpel then these charlatans that claim to release myofascial tissue seem little more than snake oil salesmen.
He mentions the jaw, but he doesn't get into the TMJ. TMJ problems are actually more often related to stress related neck problems that tinnitus.
I don't know what this guy's professional background is, but he's pretty benign
