The wire between the upper and lower plates carries the power from the coil up to the point arm. The lower plate is screwed directly to the distributor body, yes but the piece where the armored cable contacts is insulated.
The ground path for the points in the distributor would be the upper plate through the tabs/spring between the plates.
