I assume you're referring to around time index 2:40, in the "buildList" function. The purpose of that function is to create the list as a string and return it. The code that calls that function uses the returned value to display it on the page.

You'll notice that the function is called more than once, and the outputs are joined together to form a larger string. This is why it makes sense to implement the function to return the constructed string instead of placing it on the page directly.
