Some designs have the fingers coming to the theoretical edge of the PCB with a chamfer required. In this case you should not see the buss bar (stub) unless the edge alignment is off. Other designs have the fingers stopping short of the edge with the buss bars running to the edge. Depending on the chamfer, the design itself may result in a piece of the buss bars being left. In either case, exposed copper will be seen and is acceptable per IPC-A-600.
