They are not the same.  In version 1, the template gets instantiated once.
The four addressbook/address elements then get processed by the for-each.

In version 2, the template gets instantiated for each separate
/addressbook/address element, for a total of four times in your example.
Each time, the for-each gets applied to the current node, which consists of
a single address node.  So there is nothing to sort.

You can demonstrate this by adding a visible marker so you can see when the
template has been instantiated, like this

  <xsl:template match="/addressbook/address">
    --template called --
    <xsl:for-each select=".">
      <xsl:sort select="name/last-name"/>
      <p>
      <xsl:value-of select="name/last-name"/>
      </p>
    </xsl:for-each>
    </html>
  </xsl:template>

You will see the marker once for version 1, four times for version 2.
