Brake system hydraulics.

Specifically, the combination valve and master cylinder.
My understanding is that the combination valve is supposed to shift to isolate the front or rear brakes in the event of a blown hose, however, I thought this was also the whole idea behind modern master cylinders having tandem pistons, each piston feeding half of the brakes, front or rear. Yes most brake master cylinders have a common reservoir that can be drained, but they're typically divided midway up such that a leak on one side doesn't drain fluid from both.
The whole system seems very belt and suspenders, not that it would be a bad thing to have redundancy, but I just don't see the advantage.
is my understanding grossly flawed? the reason I ask, is because I'm planning on installing a line lock, and was considering an adjustable proportioning valve in the rear circuit, and eliminate the combination valve from the equation. Am I making a grand mistake by doing this?
