You're applying templates to all the child nodes after the second, and then
you're applying templates to all the child nodes that are products. These
categories presumably overlap. I haven't followed what you're trying to
achieve, but this looks very odd.

Incidentally this could be rewritten

<xsl:template match="document">
  ...
  <xsl:apply-templates select="child::node()[position() > 2]"/>
  <xsl:apply-templates select="child::product">
    <xsl:sort.../>
  </xsl:apply-templates>
</xsl:template>
