Understanding difficulties with call-template

[robert@xxxxxxxxxxxx]

I have the following code

<xsl:template name="comma-block">
<xsl:for-each select=".">
        <xsl:value-of select="."/>
<xsl:if test="not(position()=last())">, </xsl:if>
</xsl:for-each>
</xsl:template>

<xsl:template match="preferred-locations">
<xsl:element name="p">
Preferred Locations:
<xsl:call-template name="comma-block"/>
</xsl:element>
</xsl:template>

now when I call the template it correct outputs the correct nodes but
the xsl:if test doesn't work  .... position==last for all nodes.

When I inline the above code instead of using call-template the
xsl:if test works as expected.
