No, because you won't have flown around the world.
You have to travel in one direction (easterly or westerly, but are allowed to backtrack within regions (eg. LAX-MEL-AKL-SYD)).
Additionally, it is not possible to fly from South Africa to North America, meaning you have to add another region, bringing the count up to four.
