Oncidium spike from Pbulb top??

[Troythediver]

I mentioned this guy in another post. I'm updated here and hoping someone can tell me if they have ever had an oncidium spike from the top of the pbulb. And if it is a sign that I am doing something wrong.

When in bloom it does not look like an encyclia at all. It is a yellow/brown dancing lady type oncidium. The spike is actually growing. I freed it a couple of days ago and it has already straighten itself out and gotten a bit bigger.
