Nick,
That sounds like the correct glass-setting procedure. Does the driver's window actually drop the same amount as the passenger's window when you open the door?
There are quite a few micro-switches which monitor door handle, window position, etc., and it could be that one of them or perhaps the window regulator is faulty. Impossible to check without stripping down the door, although a Porsche-specific diagnostic check could help isolate the problem.
