I think the bigger holes would be needed with the 'pro kit' because of the additional air draw. Can't see any other reason they would be needed.
I ran into this with an old beckett. When I removed the lid, the water level in the skimmer would change because it couldn't exhaust the air through the air holes. After opening the holes up, it was much better and made no difference if I had the lid off or not.
