It says it right there. "If an upgrade becomes available". Yes, the majority of the time I get upgrades, but just because there are open seats doesn't mean that they are "upgradable seats".
Case and point, I am flying PHX-DCA next week and I know for a fact that there are still 2 seats left available in first. If I were to buy 2 seats in F I would get those seats. However, I have not yet been upgraded because they are holding those seats for revenue. If the seats don't sell and there aren't any CP flyers with more miles then me, then I will get upgraded at the airport.
