I can't see it matters which way round the back plates go other than where the brake pipes are in relation to the axle. It's a single leading shoe brake so whichever way round it will still be a single leading shoe brake, which way round is much more important on a twin leading shoe brake.
Because of the direction of rotation of the brake adjustment cams, with the drum off as you tighten one will try to move the shoe down the other will try to move it up. This isn't relevant because once restrained by the drum they can only move in & out (they will try to move up & down but can't move far so move out). When adjusting the brakes you should adjust till they bind, back off then press the brake pedal hard which will centre the shoes and then release the pedal and see if you can adjust further.
