The flash would have a series of pulses which fill the duration the slit passes in front of the shutter. The size of the slit WOULD have an effect on exposure. AS was done in the Olympus om system. It's simply the only way such a thing could be done. Perhaps Olympus is making it for them instead of Metz? Kind of emulateing the way you work with a flashbulb but without the initial delay.
