It looks to me like they are using nomination and appointment interchangeably. You did not receive a nomination from this MOC, thus you also would not receive an appointment charged to them.
However, if you received a nomination from another source, you would still be “in the running” from that source. And there are a few possibilities from the SAs themselves. So it isn’t “over” until you get the no from the Academy. (However, if this was your only nomination source, then it did get quite a bit harder).
Best wishes and keep the hope until you are told no from the Academy. And if that happens this cycle, then I am sure your plan B will put you on a successful path for your future! (And if an Academy remains your goal, they seem to love reapplicants!)
