Question about Basal Keiki

[Im Just Saying]

So I have read in numerous threads on here about unhealthy plants putting out basal keiki as a last ditch effort to ensure propagation of the plant. Should I be worried if a seemingly healthy plant has what looks to be a leaf like structure coming from the base? This phal I purchased in March in bloom, and re-potted it last night as the blooms fell off last week. The root system looks super healthy I had to only trim off two small roots that had a bit of rot on the end. However I was thoroughly surprised when I saw the leaf like structure coming from the base of the plant under a leaf. Is this the start of a basal keiki, and will it be able to continue to grow as it is right above the top of my medium and under an leaf on the mother plant?

Sorry the picture isn't so great, I wanted to add that when I was examining it I could see that it was something folded in half with "joints" which is why I keep referring to it as a leaf-like structure.
