This is a strange way of doing this but...

The position() is always refered to the current node set, in this case
$set inside the value-of, so this is the same as get $set that has a
position() :) this is always true. You get 111 because the value-of
always get the first node of a nodeset

Try:
<xsl:for-each select="$set">
  <xsl:variable name="pos" select="position()"/>
  <xsl:text>Iteration #</xsl:text>
  <xsl:value-of select="position()"/>
  <xsl:text> is '</xsl:text>
  <xsl:value-of select="$set[position()=$pos]"/>
  <xsl:text>'&#10;</xsl:text>
</xsl:for-each>

Or even better:
<xsl:for-each select="$set">
  <xsl:text>Iteration #</xsl:text>
  <xsl:value-of select="position()"/>
  <xsl:text> is '</xsl:text>
  <xsl:value-of select="."/>
  <xsl:text>'&#10;</xsl:text>
</xsl:for-each>
 
(...)

Hope this helps
