You don't think the airline would have left this large loophole open, did you?
You can no longer apply a non-refundable ticket for a refundable ticket. You can apply non-refundable vouchers to a refundable ticket. However, if you request a refund, the refund is always in the original form of payment, which in this case would be another non-refundable voucher.
