By vasiliy-bout:

myFullyInitialized flag is a value indicates that SessionId and corresponding options values ARE VALID. So because we cannot say anything about session validity right here then myFullyInitialized flag MUST be set to false.

On the other hand, when initUser method is called at runtime, application can rely on values specified in that call, so myFullyInitialized flag is set to true when we are initializing AuthenticationManager state and to false when manager's state is cleared.
