Wrong. Zero offset means the mounting surface is even with the centerline of the rim. A positive offset moves the mounting surface towards the spokes of the rim, moving it in ward on the car. A negative offset moves the mounting surface towards the back/open part of the rim, pushing the rim out away from the car.
