Incorrect. This is based on the common misconception called "equal transit time". Nothing forces the air on top to "catch up" to the air below. There are far more forces at play. This is why aircraft can fly (aerobatics) upside down. The angle of attack and wing shape compress air below, while displacing air above causing suction at the split. Coanda effect among other factors come in to play at the upper surface boundary layer. It is a far more involved process.
