This is because the link checker doesn't send out a referer header.
This is on the to-do list[1].

The current version does not really do the right thing in case there
is both a name and an id attribute. In this case, the id attribute was
used. I have added that to the to-do list.

For reference purposes, [2] reads:

   The id and name attributes share the same name space. This means that
   they cannot both define an anchor with the same name in the same
   document. It is permissible to use both attributes to specify an
   element's unique identifier for the following elements: A, APPLET,
   FORM, FRAME, IFRAME, IMG, and MAP. When both attributes are used on a
   single element, their values must be identical.
