The primary reason(especially for sports/supercars) is feel. With direct linkage you feel the car and feel the road, if your steering doesn't have a direct linkage to the wheels you lose feeling and have numb steering which is quite bad for performance driving. Hell the Porsche community was up in arms when the 997 came out because it was coming with electronic steering assist versus hydraulic.
People used to hate on electric power steering assist because it gave that 'numb' feeling. For any supercar that's meant to be raced/tracked it would be unheard of to remove the driver feedback by unlinking the steering, much less a Porsche.
Steering links could have broken which would have disabled it, but no way a loss of fluid alone caused a loss of steering control. The mechanical connection would have still been there.
Lets say it is a traditional power steering set up (I agree, it most likely is), then it's not unreasonable to believe that there could have been a failure in a steering line. The pumps i deal with at work can put out as much as 2200PSI, which is certainly enough to turn a small leak into a complete bust if it's leaking from the fitting/hose end.
I'm not trying to argue with you, just stating that we don't know enough to dismiss what the report is saying.
I know my Trans Am is a pain in the ass to steer when i lose power steering, i could only imagine how difficult it would be to steer it around a corner at 120+ MPH.
