The towel or pillow technique works well with ball pythons because they do the coil/hide thing as a defense, so they prefer to hide versus run if possible. The defensive abused juvenile burm I got was the same way; she was very grabby and instead of running would prefer to cling to your hand and strike at your face or stitch your arm as a defense. She was never really a runner.
The Sri Lankan python in the video was the opposite; he's a runner. My defensive boas were like this too, and it's harder to deal with that because if you hold onto them too tightly they feel confined by your hands, but you don't want to drop them either. If you notice in the video, the snake is being supported on the back of the hand versus the palm.
