Your understanding of LandscapeLeft and LandscapeRight is back to front.

The [Apple documentation](http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplication_Class/Reference/Reference.html) says...
> UIInterfaceOrientationLandscapeLeft
> The device is in landscape mode, with the device held upright and the home button on the left side.

> UIInterfaceOrientationLandscapeRight
> The device is in landscape mode, with the device held upright and the home button on the right side.
