This question looks to be written correctly, however the link that should read "this page" is extended to include all text in the question up to the next link. I can't see any error in the question, am I missing something?
Fixed by just editing the question.
Sometimes old questions have bad formatting due to bugs in the markdown handling at the time the post was last saved. A lot of bugs have been fixed over time, but some require posts to be re-rendered before the displayed state is correct.
Editing forces a fresh rendering and fixes those issues - unless the bug hasn't been fixed yet, obviously, but that was not the case for this question.
