Thats not really the point as I see it.

The point is that being in the top doesn't mean what it means on iOS. On iOS you will be able to stay in the top purely by being in the top because people use the app store much more frequently.

On the Mac app store you being in the top is more a product of a lot of other things you do.

If you hit a nerve just like you did and I to some degree did you will do well even if you aren't in the top of the app store.

At least that's how I understood it, but perhaps I am putting too much of my own bias into it.
