Indeed, the die-cutting drawings on the Post-Canada website for this stamp is not a true copy of the final product.
It is not often that they use more than one type of serpentine die-cutting for a booklet. Before this one,
Canada Post had used three different die-cutting for the EID stamp # 2998, 2998i, 2998ii (BK670)and seven types of die-cutting for the Battle of Vimi Ridge #2982 (BK666)The reason for this ????
