Having the valve open reduces backpressure in the membrane housing so all the water bypasses along the outside of the membrane, flushing it. Once the handle is turned 90 degrees, the built in restrictor creates the required amount of backpressure in the waste line to cause some of the water to get pushed through the membrane and purifying it.
