It looks like the answer has now actually been deleted, so you would appear to have been correct in flagging it as a link-only answer. So, it would seem that this issue is now mute.

However, as to *why*, only the decliner would know that. 

Nevertheless, for historical purposes, it might be worth trying to find an archived version of the page to which the link referred (using the *way back machine*, maybe), and posting a new answer with both the wayback link and the relevant contents of that said page.
