Thank you for the fix! 

I don't think I understand the bug based on your description. You say

You start saying *first iteration* and then refer to *second snippet* did you mean *second iteration*?

You say

> and would return

Can you link to the line?

Can you also point to the line we are checking `CheckingForUndefinedBehavior`?
