This has been discussed so many times on the forum and yes, it's not a bug or something that must be fixed, it's just that we intentionally decided to stick to the STANDARD terminology used by the simulator itself, which is also how thousands of AFCAD files out there has been based on (which GSX reads), which use two keystrokes, and their official definitions are:
Shift P and then 1, is called by Microsoft "Pushback Left"
Shift P and then 2, is called by Microsoft "Pushback Right"
Of course, you press Shift P and then 1, the airplane TAIL will go to the Left, and the airplane NOSE will go to the Right. And that's from the pilot's perspective, or from a top-down view.
GSX simply conforms to the simulator own standard.
Of course, from the scenery customization page, you can customize the pushback labels to indicate whatever you like, not necessarily Left or Right.
