You're grouping the <products> element by the value of the <product> 
elements that it contains. You want to group the <product> elements 
based on their value:

<products>
  <xsl:for-each-group select="/products/product" group-by=".">
    <product><xsl:value-of select="." /></product>
  </xsl:for-each-group>
</products>
