What is happening is that for each citation you are returning a
(possibly changed) version of the content. So $contentReplace is a
sequence of versions of $content.
If you want to use side effects in a loop like this you could try
replacing the return in the loop so that the value of $content is set
each time through. Something like:
for $citation at $pos in $citationlist
return
xdmp:set ($content, replace($content, $citation,$hreflist[$pos]))
