Yes, indicative of the attention deficit that seems to apply once the general principles are believed understood and the crowd rush to other more sexy problems. Field problems are generally not that easy to interpret by cause and effect thinking. Easier to figure out steady state solution and not worry too much about the initial transient which was how the system got there . Think the unsatisfactory discussion on starting vortices begins here!
However for a structure in airflow midchord flow is forced down so momentum theory is happy and the interrupted flow causes a reduced pressure behind the wing which accelerates local air. So reduced pressure and higher speed above the wing and everybody is happy
