They are indeed at odds. Apple should update their description to match 
LC's. :)

They seem consistent with one another, except that each uses a part of 
the hardware at opposite ends of the phone to define orientation.

Apple's docs are referencing the camera as the point of reference for 
orientation, while LC uses the Home button as the point of reference. So 
while "left" and "right" are used differently, you should be able to get 
the result you need in LC.

Use Apple's spec when coding in Apple tools and languages, and LC's when 
writing in LC and you should be fine.
