Is there a reason why there is an extra constant used in the admin side?

In
admin
/includes/functions/extra_functions/superglobals.php

there is this constant defined:

define('SHOW_SUPERGLOBALS_FROM_ADMIN', TRUE);

this is only used in the main function in
catalog
includes\functions\extra_functions\superglobals.php

PHP Code:
if (defined('SHOW_SUPERGLOBALS_FROM_ADMIN')){
    
// the script is being called from the admin
    
if((SHOW_SUPERGLOBALS_ADMIN == 'true')....... 
SHOW_SUPERGLOBALS_ADMIN is the constant used in the administration page. Why not just use that one and remove the overall "if"?
