Look at the back of the page.
The bottom view is the mirror image of the top view.
So instead of pin 1 being on the top left (in top picture) it would be on the top right from the bottom, and the pin order is clockwise instead of counter-clockwise.

(Why does the bottom layout picture not show the pins in order?)
