If the wind is zero the vane will be in a random position - if the pole is not perfectly vertical there may be a tendency for the vane to move, under the force of graviy, to a particular direction. The station will report the vane position regardless of wind strength. It is weewx which will 'cancel' any 'rogue' reading depending on the setting of ignore_zero_wind.
