Think about the simple linear mixing case, where dV/dl = V(lambda=1) -
V(lambda=0). The dV/dl result is *not* reporting on "two" systems, but is
reporting on the difference between the two end states. There is a single,
common, value being reported by the two groups that are otherwise
concentrating the two end states.
