If you book a non-refundable fare, the amount remains non-refundable, even if you use the funds to buy a fare that normally allows refunds. Some airlines will even prevent a refund of any amount paid over the non-refundable amount, but most will at least refund any excess over the non-refundable amount.
The non-refundable restriction is placed on the actual ticket, and just like the expiration date, then attach to any subsequent tickets.
