Info deliberately not set for US/Canada?

I don't understand why the following checks are in the module, but the end result is that !delivery_country_name, !billing_country_name, !delivery_country_code, and !billing_country_code are not set at all if the country is USA or Canada. There are four of these checks in the code. I replaced all four conditional expressions with "if (FALSE) {}" and it fixed the problem. (This is not the best fix, but I don't know what the intent of the code is so I didn't want to mess with the "else" part of the statements; this was the smallest change needed to achieve the desired result.)

if ($order['delivery_country'] == 124 || $order['delivery_country'] == 840) {
  $values['!delivery_country_name'] = ' ';
}

if ($order['billing_country'] == 124 || $order['billing_country'] == 840) {
  $values['!billing_country_name'] = ' ';
}

if ($order['delivery_country'] == 124 || $order['delivery_country'] == 840) {
  $values['!delivery_country_code'] = ' ';
}

if ($order['billing_country'] == 124 || $order['billing_country'] == 840) {
  $values['!billing_country_code'] = ' ';
}
