Wow John - good bit of digging! A lot to get through there, and a lot more to actually understand it! And I'm only a couple of paragraphs in. This is the first I've heard of this and, assuming it isn't a hoax, I'm amazed it's stayed under the radar.

I'm guessing you're right on this. It sounds as if the bolts and rope were at the top of a line of fixed ropes down onto the route. The penultimate pitch of Mescalito traverses half a ropelength to the right to the belay below the final pitch. From a point a few meters lower down Free Dawn traverses right for a couple of pitches to gain the finish of Tempest. The top of a line of fixed ropes down the whole route would be located substantially to the left [looking in] of either of these finishes - ie on a fixing route, but not on a climbing route. So, as you say, the interference with a fixing anchor shouldn't affect the route's "climbability".
I'm off to do some more reading.
