using jQuery .each() method on single-element id-selector
<p>Explaining <a href="http://blog.nemikor.com/2009/04/18/loading-a-page-into-a-dialog/" rel="nofollow">jQuery dialogs</a> in the Nemikor Blog, Scott González uses the .each() method on an id selector:</p>

<pre><code>$('#page-help').each(function() {
  var dialog = $('&lt;div&gt;&lt;/div&gt;')
    .load($(this).attr('href'))
    .dialog( ... );
  $(this).click(function() { ... });
});
</code></pre>

<p>Since an id selector can only return a single element, what is the purpose of using the .each() method? (which is normally for iterating over matched elements).</p>

<p>Is it just that there is no simpler way to execute a function for the 'page-help' element which provides access to $(this)?</p>
