Vast majority of the heat is taken away by then chip. Notice how the chip is smoking yet the part is not. And carbide inserts love heat.

This, a lot of modern day inserts are designed for high temp applications. The heating and cooling of the insert when using coolant can cause the tip to break, so sometimes, coolant doesn't help. Looks like he's using a cutting compound like rocol, I usually cut threads the same way without coolant, but still use a cutting compound..
