Is the number of spikes pre-determined?

[bwehr28]

I have a large phal that I bought in March of this year. When I bought it, it was in bloom and had 2 spikes. One spike was not staked and broke off during transport (it was a clearance orchid). I let the other spike stay in bloom. It wilted in May and I repotted it. It is now growing a new spike.

My questions is, did I screw up this orchids bloom cycle when the one spike broke during transport? Does a double spiked orchid always grow 2 spikes at once? If it does, will the spikes keep alternating bloom timing? I'm not concerns, more just curious.

Thanks as always for the help and support!
