Is it possible that when they replaced the pads, they cleared the service indicator for the wrong ones? Even still 50,000 miles seems like an error.

Wel , the rear pads wear faster for bimmers (rear wheel drive) ,concerning the break pad sensor on bmws its for emergency warning when the pad is fully worn out ; it does not measure thickness of the pads , the milage remaining you notice on the service computer is a calculated 'predicted value' by the bmw condition based service computer it aquires data from DSC & ABS system to monitor your driving braking style & thus predicting the remaining milage but i confirm you its amazingly perfect, can't be wrong
