Many guys reroute the scuppers out the transom when they restore a boat and Moesly built the 21 like that, although he was known to add one innovative wrinkle by crossing the hoses under the deck so the starboard scupper dumped out the port side and vice versa. This allowed him to keep the deck low but still not have water run in when you walk to the back to install the plugs!
The vertical scuppers appear to be a Potter creation, and may have been a cost reduction on the 20's, since he didn't have to run hoses under the rear seats and back to the transom. He installed a wedge on the bottom of the hull in front of the scupper hole, which creates a lot of suction that makes them drain very fast, probably even better than the gravity drain through the transom. Back in the mid-60's when the boats were designed, the most popular outboards weighed 300 lbs or less, so the "wet feet syndrome" is less common than it is today with the 500 lb+ 4-stroke motors! Potter raised the deck on the 20's in the mid 70's, evidently to accommodate the heavier V-6 motors that came out then.
