I think we in reality agrees, but we might have a slightly different meaning regarding acceleration.

According to Einstein a sattelite in orbit is free falling around the earth in its orbit, experiencing zero G. Standing still on the face of the earth we are experiencing 1G.

What you was describing is what most people would count as an acceleration, the (vertical) speed starts at zero, then the speed increases as the object is free falling towards the earth. And thus the object must be experiencing a G of some magnitude since it is falling faster and faster. But this acceleration is only perceived and is dependent on the observer standing still and experiencing 1G. An observer free falling together with the object would see no acceleration of the object and would therefore conclude the object was not under any acceleration and thus experiencing zero G.
