Can I assign same user role for two different users?

In my application, I have a user role InsideSalesmanager. I assign it for two different users. Now, I want to retrieve the login user name. I am using the below condition. But, I am getting the first user name even though I am logined as second user. Can any one help me?

[System.UserRoles/System.UserRole/System.UserRoles = '[%CurrentUser%]'
 and Active]
