There's some logic to it: it suggests that <xsl:break> within an ordinary
<xsl:for-each> could also be defined cleanly, as "discard any result nodes
generated beyond this point". Could be useful:

<xsl:template match="h1">
  <section>
    <xsl:for-each select="following-sibling::*">
      <xsl:if test="h1"><xsl:break/></xsl:if>
      <xsl:apply-templates/>
    </xsl:for-each>
  </section>
</xsl:template>

An alternative to saxon:leading(). I quite like it. I wouldn't like it if
you could achieve this effect by writing a function and not achieve the same
effect inline.
