Code confusion – Registering and displaying a new widget area

[mohitb]

Hi,

I was referring to a tutorial on how to register and display a widget area in a custom front page. While I understand the process of registering a widget area using genesis_register_widget_area ($args), was a little confused about the code (shown at the bottom of this post) used to display the widget area in front_page.php.

If I modify the code below to just use the genesis_after_header hook, it seems to work exactly the same way.

So is there something different going on when I use the genesis_meta hook to call the custom function my_homepage_setup and then use the genesis_after_header hook within the called function?

add_action( 'genesis_meta', 'my_homepage_setup' );
/**
 * Add widget support for homepage.
 *
 */
function my_homepage_setup() {

	if ( is_active_sidebar( 'front-page-1' ) )  {

		 //* Add front page 1 widget
		add_action( 'genesis_after_header', 'display_front_page_1_widget' );

	}
}

// Add markup to display front page widgets.
function display_front_page_1_widget() {

	genesis_widget_area( 'front-page-1', array(
		'before' => '<div class="front-page-1-widget"><div class="wrap">',
		'after'  => '</div></div>',
	) );

}
