The key to the finish is having two holes where a 240+ yard approach to a firm green is the required or at least normative play. For elite players today that means a very long hole but it is the long iron/fairway wood approach and not par designation that matters.
The important element is having scores of 3,4,5 and 6 truly in play. Hard to get four possible scores in play for Tour players if they can approach the green with 8-iron or less. I suppose a 270 yard Par 3 with copious hazards could perhaps bring 2,3,4,5 into reasonably likely play as a closing hole.
