What's the purpose of the delegate creation in this MSDN code sample?

[amt528]

The following code sample is in the docs about subscribing to selection events with the Automation API:

///--------------------------------------------------------------------
/// <summary>
/// Subscribe to the selection item events of interest.
/// </summary>
/// <param name="selectionItem">
/// Automation element that supports SelectionItemPattern and is
/// a child of a selection container that supports SelectionPattern
/// </param>
/// <remarks>
/// The events are raised by the SelectionItem elements,
/// not the Selection container.
/// </remarks>
///--------------------------------------------------------------------
private void SetSelectionEventHandlers
(AutomationElement selectionItem)
{
AutomationEventHandler selectionHandler =
new AutomationEventHandler(SelectionHandler);

Automation.AddAutomationEventHandler(
SelectionItemPattern.ElementSelectedEvent,
selectionItem,
TreeScope.Element,
SelectionHandler);
Automation.AddAutomationEventHandler(
SelectionItemPattern.ElementAddedToSelectionEvent,
selectionItem,
TreeScope.Element,
SelectionHandler);
Automation.AddAutomationEventHandler(
SelectionItemPattern.ElementRemovedFromSelectionEvent,
selectionItem,
TreeScope.Element,
SelectionHandler);
}

private void SelectionHandler(object src, AutomationEventArgs e)
{
// TODO: event handling
}


At the beginning of SetSelectionEventHandlers, the delegate selectionHandler is created and never used again. I'm wondering what the purpose of that is. Thanks for any input.
