All three blades go over the frame.

I suspect that they use three wiper blades of the size they do to overcome some silly legislation about the percentage area of the screen that must be wiped.

because the blade is partially clear of the screen when it is over the frame, it will never wipe properly, there will always be a miss.

I'm convinced that shorter blades would actually work better.

I also think that the blades will eventually mark / wear the chrome on the bottom of the frame.
