Custom Providers and the Permissions page

Hello. I have a custom MembershipProvider and RoleProvider. I go to the Global Permissions page on the dashboard and am loggged in via the Default Provider. When I step through the code I see that it is calling CustomMembershipProvider.GetUser with the value "231d2ec2-b333-40f3-b7fe-cc15c262abf2" and other similar ones.
What I don't understand is why it is calling GetUser with those values, that is a Role defined in SecurityConfig, "<role id="231d2ec2-b333-40f3-b7fe-cc15c262abf2" name="Designers" />". Is it calling GetUser on every possible value? Should my GetUser method be expected to find users based on a Role id? Other values were not in the SecurityConfig so I don't know where they came from.
I had based my code on the example I found here.
I am running Sitefinity 4.2
