Or rather none of them. Here's a solution using just apply-templates:

  <xsl:template match="fgc_list">
    <xsl:copy>
      <xsl:apply-templates select="fnc"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="fnc">
    <xsl:copy-of select="." />
    <xsl:copy-of select="../figure[@parent-id eq current()/@id]" />
  </xsl:template>

The proposed solution inserts figure3 at another position than 
specified: just after its parent fgc2.1, rather than after fgc2.1.1.  Is 
this ok?  I couldn't devise a rule that inserts figure4 immediately 
after its parent fgc2.1.2, while figure3 won't be inserted immediately 
after its parent but after the first of fgc2.1's two children.

Proposed solution seems to be in accordance with this rule.
