Except that that latter template will get the contents of the position and 
all its descendants.  That would give

contents-of-1-2-3-and-4
contents-of-5
contents-of-2-and-3
contents-of-4
contents-of-3

<xsl:template match="position" mode="visit">
  <xsl:apply-templates select="text()"/>
</xsl:template>

might be better.

(Of course, Mike's example was only illustrative, but pedantry is the order 
of the day.)
