Enpassant, like castling, is not accounted for during generation of the bitbases.
Not accounted for at all? Or are the ep positions themselves just not stored?

Yes I understand it, what I am actually trying to address (my mistake) is that of all the positions that I found, this is the first time that e.p capture is not possible after a 2-step pawn push.
Yes, now I see what you meant. Thanks Ferdinand, for your help pinning it down.
