Short answer : it is all about achieving the performance when retrieving large cube views.
I would suggest that you play around the options of suppression to fully understand what they do and how they display.
Longer Answer: Cube view paging is only applied to the data explorer view of a cube view and is used to enhance the performance of cube views containing more than 10,000 unsuppressed rows. The cube view will attempt to return up to 2000 unsuppressed rows within a maximum processing time of 20 seconds. The purpose of paging is to protect the server from large cube views that could affect application performance.
To set the properties, on the Cube Views page, under Cube View Groups, select a cube view.
Go to General Settings > Common. The following settings are available.
