System Blue connector S1 3-4 ?

running my System Blue for first experiments and set-up tests, waiting for my GPS antenna.

One question about the on-board connector S1 on PCB 19.3. By default 1-2 and 5-6 are jumpered but what about 3-4?
The schematic is telling me that a lot of IC's are connected to VDD but a jumper is needed on 3-4.

Obviously VDD is connected to the IC's since they are working. Is there any change in the PCB connecting them to VDD without the jumper or is there any further meaning for this jumper?
