I agree with you by providing the rght condition and nutrients.
If its still in flowering mode it will producd a spike in any node, provided it was given a proper care.
The leaves on the spike, is what we call a keiki or a baby. CONGRATULATIONS!!!
Phalaenopsis has tendencies to produce keiki on spike, and some are basal keiki. Wait until it grows its own roots around 2 inches long before removing it from the spike. And planting it as any regular phal seedlings.
