As far as releasing the pedal., I was talking about the clutch, not the brake. I do understand what you are saying about the brake returning a little fluid.
My question was, do you think that if you lost your clutch fluid because of a brake line leak in the single reservoir system, would you have enough in the clutch master to shift the car for a while? If it was to return some fluid to the reservoir every time you released the pedal, you would be screwed.

If I understood Bob correctly, it sounds like the clutch has it's own fluid storage in the BMW reservoir. Without having seen one, what I suspect is that there are two dividers in the bottom half of the reservoir that creates 3 fluid chambers. As long as the fluid level in the reservoir is maintained above the dividers, all the chambers stay full. If the front brakes loose a caliper seal and fluid, the reservoir level would fall to the level of the dividers and the fluid in the front brake chamber would continue to fall until the master cylinder sucks air. But the rear brake chambers and the clutch chamber would still have their fluid chambers full up to the dividers and continue to operate normally and have some fluid reserve. Not sure if this is correct but sounds like the approach.
You should not lose the clutch due to losing one of your brake circuits. You should not lose the brakes due to losing the clutch circuit. All three have some independence and redundancy in terms of reservoir storage if one does develop a leak.
