This happens because the $Description variable is evaluated as text before the 
page is saved to a file, not when it is requested. And before the page is 
saved, the $LastModified and $LastModifiedBy variables contain the previous 
timestamp and the previous author.

If you set the part "last modified on {$LastModified} by {$LastModifiedBy}" in 
the title= attribute of the link, it should work :

$LinkPageExistsFmt="<a class='wikilink' title='{\$Description} - last modified 
on {\$LastModified} by {\$LastModifiedBy}' href='\$LinkUrl'>\$LinkText</a>";

(:description My Page 2:)

Note that having apostrophes in your description may break your link titles 
and produce invalid HTML. You can fix this by adding to config.php :

  $FmtPV['$Description'] = 'htmlspecialchars(@$page["description"],
