Yes, technically true but but we're also dealing with one one of the most aerodynamically retarded forms of transportation there is. The 950 maybe more so than most.
Check out the Buell below. They have a ton of money in their wind tunnel testing and that duct is for high pressure intake - far more than just reducing the pressure behind the screen. You're not looking to do anything but reduce the pressure differential
which will reduce the buffeting. While endless speculation is fun (and what the internet is built on after porn of course) I've done this and it works - 24,000 miles so far with an XD.
