not to use setTimeout inside arrow function
You say don't use setTimeout inside an arrow function, but your code example is using an arrow function inside setTimeout as a callback. That's the exact opposite. Do you have a timestamp in that video where he speaks of this?

Anyway, to your point, a lot of people get confused about this and lexical scope. I have no idea why there's so much disinformation in JavaScript's ecosystem. But alas, there is. When in doubt, trust what MDN says or, as in this case, your own testing.
From MDN:
Arrow functions don't have their own bindings to this
Which means, arrow functions don't bind their own scope. They inherit it from the parent one. A regular function will always define its this value. The value of this is determined by how a function is called. To put it simply, the this in the setTimeout function for the regular anonymous function is using the this of setTimeout's scope because setTimeout is what calls the function.

Don't know what the dude said in the video because I didn't watch the whole 30 mins. But, that's the reason for the behavior you're seeing.
