This is because you've only defined branch within the priority="5" template,
so it will only be scoped there.  You also need to scope it within the
priority="4" template:

<xsl:template match="s//ng//*" priority="4">
  <xsl:variable name="branch">right</xsl:variable>
  <xsl:copy>
    <xsl:attribute name="branch"><xsl:value-of
select="$branch"/></xsl:attribute>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

Question:  is $branch always equal to "right"?  If so, you can define the
variable at the "top" i.e. as a direct child of the xsl:stylesheet element.
Then it will be scoped throughout...
