you need to get your terms straight. His diagram shows a wing with a line through it. This is the chord line and that is what is used to define angles of attack and angles of incidence.
By definition that wing produces lift at a 0 degree angle of attack.
Many sailplane wings will fly at 0 and slight negative angles of attack.
The angle of attack is the angle formed by the chord line and relative wind.
The angle of incidence if formed by the the chord line and the longitudinal axis of the fuselage.
