Does anyone know if the Park Tool Cyclone Chain Scrubber works on a bike fitted with a BBSxx?

The reason I ask, is that once the device is fitted, the user has to back pedal the chain for the system to work.
Due to the freewheel in the BBSxx, the chain does not move when back pedaling. So I need to know if it will still work whilst rotating the pedals forward, as this is the only way of moving the chain through the scrubber.
The rear wheel will be off the ground of course
