Yes, check the definitions of the author's theoretical max ball calculation on the first page gravitational acceleration determines the 'hang time' of a ball for a given value of hand acceleration. So holding everything else the same the same person with the same ability to throw 9 balls at g=-9.8m/s^2 would throw the balls higher on the moon giving them more room in their pattern for more balls.
