That number is not for devices not actively adressed (whathever that means) but for devices that do not have power profile accepted by host. On the other hand it is slightly unclear how that is meant because that is awfully close to the power required for correct device-side Full speed USB termination network. Thus interpretation that I use is that before enumeration the device as a whole should not draw more than 1mA from VBUS.
