Interestingly enough, I just finished roughing a large house with two 200-amp disconnects feeding a pair of remotely-mounted main-lug panels. I ran the #6 solid copper from one rod, into the first disconnect, back out and into the second disconnect, and then out to the second rod.
As the wire was unbroken from rod to rod, each disconnect had two paths to ground, via two rods. The inspector said it was quite unorthodox, but it satisfied him and met the intention and letter of the requirements.
By the way, code requires the two rods to be at least six feet apart.
