Ok, I answered my own question but I do not understand why.  

If I create a return URL with the contents of $referer, it points to my 
current page and not the prior even though if I put a [dump] in the 
destination page, the referer is still showing the prior page...

The link in question is:
    <a href="[calc]return $referer;[/calc]">Click HERE to adjust your 
search</a>
