The fide rule doesn't have to say anything. If the ep status changes, then a pawn _must_ have been moved. :) That would have reset the counter immediately. Castling is irrelevant. The rule says "no capture or pawn move for 50 moves." It doesn't mention castling status. EP is included since to have an EP capture you had to move a pawn and that resets the counter.
