Well, he introduced variables and functions, so I think it's worth mentioning because should they want to use it, they may think they are used the same way as many other languages and wonder why the variable is not updated.
Since this is geared to people coming from Javascript, I'm assuming they already know when or when not use a global variable.

Okay, good points, thanks. The argument, that people should already know what they are doing, convinced me. So maybe, yes, it is worth to mention it.
