Pro Sites - Quota for levels

In Pro Sites on the settings page it says "Allows you to limit the number of post types for selected Pro Site levels" - am I right in thinking I have to set "level" and "quota" for each level then press save, where can I display what they are?

For example:
Free Account = 5 pages/products
Silver Account = 20 pages/products
Gold Account = 100 pages/products
