What output will this app inventor code generate?

I am pretty sure this question is going to be flagged but I am in huge confusion from this questions. It is from a sample question paper of my App Development Fundamentals. This is the procedure block: and this is the part which calls that procedure:

The questions is: What value will be displayed in the label lblOutput after the button has been clicked according to the following code for the button’s Click event

I know a little about programming and my best guess is that this procedure will sort the numbers in ascending order but I am not sure because of the first if block. It says if item < select item from list (finalList) with index position (which is currently 1). The finalList is empty, isn't it? Then wouldn't it show an error? I am confused in that part.

Also, there's an another part of this question: **What would be a more appropriate name for the procedure (based on its behaviour)? **

I am guessing the answer would be: ArrangeInAscendingOrder or something like that.

Please someone clarify about that first if block.

Thank you.
