beginGeneratingDeviceOrientationNotifications idiosyncrasy?

Question

Does beginGeneratingDeviceOrientationNotificationsreset the status bar back to Portrait orientation?

In my app, logging o and p below:

UIInterfaceOrientation o = [[UIApplication sharedApplication] statusBarOrientation];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
UIInterfaceOrientation p = [[UIApplication sharedApplication] statusBarOrientation];

I get:

o = UIInterfaceOrientationLandscapeRight
p = UIInterfaceOrientationPortrait

Is it me, or is this expected behavior? Where this bites me is that after I beginGeneratingOrientationNotifications, my notification routine gets called twice back to back, once for UIInterfaceOrientationPortrait and then UIInterfaceOrientationLandscapeRight - which is the actual orientation of the iPhone at that moment.

Regardless of how the iPhone is held, I get one UIInterfaceOrientationPortrait notification before I get the correct one.

Ideas?

On iphone, the app is launched in the portrait mode and then rotated to the specified orientation.
