It seems like when you are in supercruise your position is tracked locally. When you disconnect or return to the menu, you don't always end up at the same spot in the system you are in. In essence, to the ED servers your location in supercruise is meaningless. They just wait for your client to tell them which local instance you want to enter or if you have jumped to another supercruise instance (in another system). Seems like it would have been trivial to have a trigger that requests an instance change to a new system when your locally tracked distance from the star you are near is farther than a star you are aiming at. Oh well.
A bit off topic: if supercruise location is indeed tracked locally, I wonder how long it will be before someone figures out how to hack and spoof it for instant supercruise?
