Confused order total process without return array on checkout confirmation page

[tgely]

Following lines not use the possibilities

oscommerce2/catalog/checkout_confirmation.php

Line 77 in de0e97d

$order_total_modules->process();

oscommerce2/catalog/includes/classes/order_total.php

Line 40 in de0e97d

function process() {

Return process array is not computing by this way later in the flow.
