Does fungal infection induce keiki production?

[SG in CR]

I was wondering if other people have observed something that I've noticed.
I've had several times where the base of a p-bulb got infected with something, I'm guessing fungus, and the p-bulb developed a keiki up on the still healthy part of the p-bulb. Most of the time the roots/base will start a new shoot as well. I've had this happen now with Aspasia, Prostecha, Mormodes and Catasetums. Which is great in a way, I got to start a new plant.
But if I take a sterilized blade and cut the same sort of piece off it will slowly wither away over the course of months without ever making any new growths. It seems to me that the infection somehow is giving the plant a signal to start growing a keiki.
