Why is "return items" outside of the for loop?

I tried running the code with "return items" inside the for loop curly brackets, and only the first item on the list displayed on the page. Then I rewrote it with the return items outside the for loop (same as Guil's) and the full list displayed. Can someone explain to me why this happened?

Esther AlQaisi este great work experimenting! Only one item is returned because the return statement ends the function. When placed outside, the entire loop can run before return is called.

I knew there was an answer I was missing! Thank you, that makes sense. And now I remember Guil mentioning that in a previous lesson.
