All airflow will want to move from a high pressure to a low pressure, so if the point of the lowest pressure is at the point of maximum camber, the airflow will accelerate from the LE until it reaches the point of maximum camber (lowest pressure). Now it encounters the adverse pressure gradient as it moves further aft (pressure increasing as you move towards the TE) it slows down and eventually gets so slow that it separates from the top surface.

As you increase angle of attack the airflow reads the point of maximum camber as moving forward, so the point of lowest pressure moves forward (CP moves forward) the adverse pressure gradient gets worse and the air flow separates further forward.

So at small angles of attack the separation point is virtually on the TE and as the CP moves forward, as angle of attack increases, the separation point also moves forward.
