I believe what Andy is saying is that this global only functions properly when viewed through one of the cgis such as page.cgi. In static mode, when people are browing the site with just the "html" files, since the file are all generated beforehand there is no ability for the html to know at viewing time what links the user has added or owns.

It is possible for links sql to generate php pages which are dynamic, unlike the html pages, which can detect the status of login of the user and then pull up the appropriate information but I don't know offhand how to do this (as I do not code php ;)
