Lots of people assume so. But its not how it actually works. Dual

ability to vary the relative pressures to some extent as the back end
rises up.

That sounds more like brake effort distribution rather than dual
circuit. I thought the latter had one diagonal front/rear wheel on
each of the two circuits.

Dual circuit brakes have 2 master cylinders built into one, with 2
separate circuits coming out to the wheels. On some cars the circuits
are split front/rear, on some theyre diagonal split. What most people
dont seem to realise is that due to the design of the master cylinder,
a leak anywhere on the entire system still results in total failure.
