Can't see the issue here.
They will have gotten a decent price as launch customer, and are to replace some GE powered 747s with newer GE powered 747s. For the same reason I would expect Air France to dip their toe into the 748I pond before much longer.
I still think if Boeing had offered to build it with a Trent derivative offered as well they could have picked up additional sales by now. That's a whole new debate though and probably won't have much effect in the long term on eventual units shifted.
