Phragmipedium bloom how they die?

[Zoren]

I'm new to growing phrag orchids. Iv'e gotten help from members as to how to attend to them properly, thank you members. I'm blown away that this morning when I looked at my orchids my phrag - Don Wimber bloom had just fell of (it did not wilt as most orchids do). There is another bud that is progressing but not ready to flower. My question is: "Is this the way phrag flowers die/replace/generate new flowers or is there something wrong with phrag"? If anyone has an answer or can give me some suggestions I would appreciate your help. I'm including an attachment so you can see the flower. Thanking members in advanced...Zoren....
