Spot on! I should've put "carotid choke" in quotations as it is being tossed around worse than a Kardashian at a Ray J party. I should've tightened that up a little better so it reads differently. I overlooked the entire audience of this site and did not mean to confuse anyone.
My intention was to explain that the use of a carotid control technique is not to affect the respiratory system, rather it is to interrupt the vascular one in order to subdue a subject. Arm bar chokes, OTOH, do a good bit of damage to the trachea. I'm not a big fan of them. Besides, they're not a lot of fun to train if you're the recipient.
Getting back on track,
Ryron and Rener Gracie released their analysis of this exact situation on YouTube. I don't run in their immediate circle, but respect their instruction. I train with Royce and Rodrigo and they are the only ones who have ever promoted me in jiu jitsu. My instructor certifications are in Krav Maga and Kali.
