You can use two forms of payment on a United ticket. FFC counts as one, and an ETC counts as one. What you described only worked because the total of FFC + ETC value covered the ticket cost. If it hadn't, and you needed to put part of it onto a credit card, you wouldn't have been able to make it work.
