Can't say I've thought of it before now, but it makes perfect sense.
My parents' home is a turn of the century bungalow in South Florida, and has survived every hurricane since with zero structural damage (there is no evidence of repair). To make that feat even more interesting, their house is located on a corner lot at an intersection of a split roadway, with a central canal, that results in about 85 yards of open ground to the east, which is the worst imaginable configuration for hurricane winds on the north side of an Atlantic storm (the worst winds).
So, what's so special about their house? It's elevated about 18" off the ground. Around the perimeter of the home (which is almost a perfect square, there is lattice work covering the openings at the base of the structure. After the first hurricane of the 2004 season, we noticed that the lattice work on the east-facing side of the house had all been ripped from it's (screwed, not nailed) mounts and pushed 10-15 feet back under the house where it laid down and allowed the air to pass through.
I stayed at the house with my parents during all the storms of the 2004 season (three total), and what I experienced was remarkable. Rather than stand bluntly against the winds, the house allowed the pressure to "breath" through it. That's how it had survived all these years. Well, that and it's made of heart pine and lumber that was cut prior to the advent of "dimensional lumber" :)
This design modification of this HUMVEE works on a similar principle. Got a pressure wave problem? Don't try to stop it, just give it somewhere to go. That's the great thing about air pressure, it seeks the path of least resistance.
