Any upsidedown A in the set of all real characters used in academia would immediately illicit mathematical memories.

Nope, it means "for any" as in no matter which one you choose it will be correct.

I sit corrected. It's used as an arbitrary singular value within the proof, so for any always felt more appropriate.
