Yes, but unless the answer was edited before the link to HN was posted, the user specifically said you should only do it if you _really_ intend to make a request, not just generate a url. It is conceivable you'd want to log the request or something and hence reference the url after the request call. Yeah, it is a bad answer to the question as stated, but it has a logic to it considering what might be the real motivation behind the question.

EDIT: Apparently the answer was edited by another user just recently making the clarification.
