Draw a line on the screen from top to bottom. You interpreted "rotate away" as turning it around this axis, which is the same axis you used for the 90-degree clockwise turn. You end up with the screen right-side-up, just facing away from you. It's the same thing I intuitively did.

Now draw a line on the screen from left to right. "Rotate away" by turning the phone around this new axis - so the top of the phone moves away from you, and the bottom of the phone moves closer to you. You end up with the screen upside-down, and also facing away from you.
