I think when a reference (list or not) is created, the listeners have to be called. So if there is a matching service in the osgi registry, the listener bind method will be called (once for an unary reference or once for each object in the list), but if there's no matching service, the unbind method will be called. This is to make sure your listener is updated wrt to the current state when starting.
