They're servo action, so are designed to pivot as they are applied to multiply the braking force. The short front shoe enables this servo action to work better. Non-servo action brakes of earlier cars (1930's and '40's) have all shoes the same length and the wheel cylinder moves the top of each shoe outward. Not nearly stopping power of 1950's-'70's servo action drum brakes.
