On the screen you will see 2 lugs at the bottom, one left one right. Use either one to lift the screen bottom upwards, you can then move it away from the camera slightly if required, and rotate for upward viewing.
Additionally, you can just use the lug on the screen top left to fold it downwards.
I believe the Olympus that the OP was talking about can't do what the Z8 can in these pictures that you post. I think it's the reason for the complicated mechanism as well as not true full articulating.
