When I was taught, the emphasis was never the timing of the air reaching the trailing edge, the emphasis was on the fact that the speed over the air foil is faster than the below it. That's about the most important aspect of it. Now it is illogical for the air to reach the trailing edge at the same time, the air traveling at the top of the foil reaches the trailing edge a little sooner than the bottom air.
