Fuel mixture has mass. A higher velocity gas has more kinetic energy than a gas moving at a slower velocity. This aids cylinder filling. Add what Paul told you about a higher duration cam is going to have a longer duration, it is easy to see why the SC cam is much more effective in cylinder filling than the 930 cam. Even though the piston is traveling towards TDC, the filling is continuing because of inertia.
