Shimano Nexus 7 problems

I notice that my second-hand Nexus 7 hub - model SG-7R50 (printed on the hub) does not freewheel much at all.

Furthermore if I pedal backwards the wheel starts turning backwards as well - I don't believe that this is a coaster brake model.

Would this be a symptom of a faulty hub? Would an oil replacement fix the problem?
