I ran into a similar problem and never did figure out why
the TOC included references to elements that were excluded.

I solved my problem by creating a small stylesheet to first
filter my source file to a temporary xml file with the
elements excluded, and then process the resulting temp file
with the standard Docbook stylesheets.  That way I didn't
need any customization at all, and the Docbook stylesheets
had no knowledge of the excluded elements.  Here is my prefilter
stylesheet adapted to your needs:

<?xml version='1.0'?>
<xsl:stylesheet
          xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
          version='1.0'>
<xsl:output method="xml"/>

<xsl:template match="*|/">
        <xsl:copy>
                <xsl:copy-of select="@*"/>
                <xsl:apply-templates/>
        </xsl:copy>
</xsl:template>

<xsl:template match="*[@condition='long']">
</xsl:template>

</xsl:stylesheet>
