That is Muenchian grouping, used with XSLT 1.0, read more on that here: 
<URL:http://www.jenitennison.com/xslt/grouping/index.xml>

But note that you don't need that approach if you use XSLT 2.0, there 
you can use
  <xsl:for-each-group select="sampleResult" group-by="@label">
    <xsl:value-of select="current-grouping-key()"/>
    <xsl:for-each select="current-group()">
which is hopefully clearer.
