I think it does cause - the name is almost an allusion as to how to do it, incorrectly. It's amazing but - even at the highest level - there's dudes that do these techniques wrong. Remember that dude Ian Entwistle in the UFC? Dude didn't actually know how to finish a heel hook. His last fight - a loss, he put himself perfectly in the position time and again, but couldn't actually finish it. I think a better name would be, the "Achilles Bend". That would be similar to its sister lock, the "Achilles Crush" - which is called an achilles lock. Primarily because - dudes try and torque the heel across their body - which is wrong. It's finished via hooking around the heel, and then pulling it towards your head - thus bending the achilles; this then travels up the leg to the knee. Okay - Achilles Bend sounds kind of lame compared to Heel Hook but - not being able to finish what is the most effective and efficient submission in a high level professional contest - is equally as lame.
