Thanks, Xavier, you are right.

Here is the version I wrote to fix this problem:

<results>
   {
     let $a := doc("http://www.bn.com/bib/bib.xml")//author
     for $last in distinct-values($a/last),
         $first in distinct-values($a[last=$last]/first)
     order by $last, $first
     return
         <result>
             <author>
                <last>{ $last }</last>
                <first>{ $first }</first>
             </author>
             {
                 for $b in doc("http://www.bn.com/bib.xml")/bib/book
                 where some $ba in $b/author
                       satisfies ($ba/last = $last and $ba/first=$first)
                 return $b/title
             }
         </result>
   }
</results>
