woocommerce hook

Hey James,

May I ask why added the same hook in /inc/woocommerce/hooks.php in ver 1.4.3?

add_action( 'woocommerce_after_shop_loop',			'storefront_sorting_wrapper',				9 );
add_action( 'woocommerce_after_shop_loop', 			'woocommerce_catalog_ordering', 			10 );
add_action( 'woocommerce_after_shop_loop', 			'woocommerce_result_count', 				20 );
add_action( 'woocommerce_after_shop_loop', 			'woocommerce_pagination', 					30 );
add_action( 'woocommerce_after_shop_loop',			'storefront_sorting_wrapper_close',			31 );

add_action( 'woocommerce_before_shop_loop',			'storefront_sorting_wrapper',				9 );
add_action( 'woocommerce_before_shop_loop', 		'woocommerce_catalog_ordering', 			10 );
add_action( 'woocommerce_before_shop_loop', 		'woocommerce_result_count', 				20 );
add_action( 'woocommerce_before_shop_loop', 		'woocommerce_pagination', 					30 );
add_action( 'woocommerce_before_shop_loop',			'storefront_sorting_wrapper_close',			31 );
