 In an extreme case, the airflow traveling perpendicular could actually cause a vacuum in the pitot tube.
 
There's no such thing as vacuum only lack pressure !  :) Boy you should see the fights that that comment causes on my Automotive chat room.

While recently evaluating engine / prop combinations (very top secret), I noted something that looks useful regarding snaps. During both up and downline snaps the speed signal drops to zero for a period of time roughly equivalent to snap duration. It appears that possibly airflow separation from the wing includes the pitot tube. Upline snaps also show a marked decline in ascent rate during the snap.
