Vocabulary with Handsome Jack: Choking and Strangulation

In the recently released video game, Borderlands 2, a discussion occurs between the antagonist and his assistant regarding the difference between choking and strangulation. Below is the best link I could find to the  conversation, which begins at the 17 minute mark. If you have yet to finish the game, the segment itself does not really contain any spoilers. The video before it does, so beware.

For people who cannot click the link, here is a transcript of the discussion:

Handsome Jack: Jimmy, please make a note: I'm strangling Mister Moorin for bringing up my wife.

Mister Blake: Choked... Mister Moorin...

Handsome Jack: No, no, Jimmy, choking is something you do when you eat too fast. As I'm crushing Mister Moorin's windpipe with my watch chain, what I'm doing is actually referred to as strangling.

It is a distinction that had never really occurred to me before. By most definitions, the two words are synonymous. The real difference comes from the specificity of "strangulation":

Choking: have severe difficulty in breathing because of a constricted or obstructed throat or a lack of air. Hinder or obstruct the breathing of (a person or animal) by choking.

Strangle/Strangulation: squeeze or constrict the neck of (a person or animal), especially so as to cause death.
Oxford Online Dictionary

While someone who is being strangled is also being choked, it is not always true that someone who is being choked is being strangled. Mister Blake's choice in words is not incorrect, but it is less precise and unacceptable to Handsome Jack. Even if Mister Blake recognized this, he was probably wise not to have argued.
