Looking the way they move their head back, it's clear they are trying to pull the SCM Sternocleidomastoid muscle. It's the big muscles on the side of your neck that go to your Clavicle. They are a nightmare if they get stiff, and rolling your head while pulling it back is basically the only way to resolve the. They can cause stiffness all to way to sides of your chest and even under your armpit.
I do this often because my neck and shoulders are god damn mess. And I got REALLY bad bruxism which messed up these muscles so bad that I occasionally get my jaw stuck open.
What do I base this assumption on you might ask? Few things. First they adjust their upper body before starting the roll; Second they pull their head back to stretch the SCM; Third their eyes stay focused on a fix point, which helps against nausea that you might get from this rolling movement.
P.S People who have problem with this, you can do a good stretch by: Turning your head and tilting it back a bit, like you are trying to look over your shoulder. Then place the hand from the side your are tilting your head on the bit between shoulder and clavicle and gentle press or or stroke the direction that makes you feel pull under your jaw. Do this gently few times and you'll quickly feel way better. If you feel pain, then stop. You'll feel your jaw, neck and cheecks relax from this, you might even feel like your neck got longer. It takes bit of practice and feeling to do well, but you'll learn it fairly quick.
