2 Predicates in 1 for-each, possible?

Hello,

Allow me to ask a question about 2 predicates in 1 for-each.

I have this xml-file:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="persons01.xsl"?>

<root>
 <organisation>
  <communication>
   <email>
    <emailaddress>e-mail@xxxxxxx(1)</emailaddress>
   </email>
  </communication>
  <communication2>
   <emailaddress2>e-mail@xxxxxxx(2)</emailaddress2>
  </communication2>
 </organisation>
 <organisation>
  <communication>
   <email>
    <emailaddress>e-mail@xxxxxx(1)</emailaddress>
   </email>
  </communication>
  <communication2>
   <emailaddress2>e-mail@xxxxxx(2)</emailaddress2>
  </communication2>
 </organisation>
</root>

I use this stylesheet to collect some information:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="xml" indent="yes"/>
 <xsl:template match="/">
  <document>
   <xsl:for-each select="//communication/email[emailaddress or
//communication2[emailaddress2]]">
    <xsl:sort select="."/>
    <xsl:value-of select="."/>
    <xsl:if test="position() != last()">,
    </xsl:if>
   </xsl:for-each>
  </document>
 </xsl:template>
</xsl:stylesheet>

I expected to get the following result:
e-mail@xxxxxxx(1), e-mail@xxxxxxx(2), e-mail@xxxxxx(1), e-mail@xxxxxx(2)

But what I get is this:
e-mail@xxxxxxx(1) , e-mail@xxxxxx(1)

It is obvious there is something wrong in my for-each-statement, but what?

Any help is this is welcome.

Kind regards,
Bert
