The rule 4.2 should read:
'No piece, except the knight (Article 5.5), may cross a square occupied
by another piece.'
instead of:
'No piece, except the rook when castling (Article 5.1(b)) and the knight
(Article 5.5), may cross a square occupied by another piece.'
-- since there is no legal move in which a rook crosses a square occupied
by another piece -- EVEN WHEN CASTLING.
