You are right. According to fide roles, it's not the castling rights that count,
but the castling moves. Since the same possible moves occur after 1.. h7, it's a
draw. You couldn't castle before (bishop, knight) or after Rh7 (rook moved), so
the position is the same. fe When there is a "ep move" wich can't be done
because of a pinned piece, the position before ep would also be counted the
same.
