Oncidium hybrid throwing multiple new growths!

[NYCorchidman]

This plant ( heaven scent) developed two little new growths on each of the two pbs last november. For some reason, only one of the two growths continued to grow leaving the other ones at hault.
Today I checked again and noticed that one of the ps is growing a thrid new growth.

This is quite intersting to me. Why would it stop developing the first shoot, focus on growing the second shoot, and now starting a third one?

Whatever the reason, I hope they all grow nicely because more growths only means more flower spikes in the future when those growths mature.

The first two pictures are from last november. You can see four little shoots at the bottom of the pbs.
Then the third picture is from today.
Staring from the left, you can count up to five.
The third one from the left is the newest growth.
