The levers should always be working towards the vertical position to ensure maximum leverage, never away from it. If the lever is vertical to start with, in line with the king pin, the brakes will be less effective the further they are pulled on. The amount that the lever is inclined is dependant on the cam and the shoes.
The brake cables and cams look like modern replacements, sometimes these are too stiff/not properly fitted/require fettling. That's why the cable is bending, which you have correctly identified as a problem. The cable should be a good fit on the ball of the lever at all angles and the components may need to be fettled to achieve this.
