You are correct (as usual). That is just the way it works. There are two contacts side-by-side in the center of the bulb socket for one end of each filament, and the threaded outer portion is the common for the other ends of the filaments (this end is the non-switched side, directly connected to the power source). The switch selects first the low wattage filament, then the high wattage filament, then both, then off.

Inside are two filaments of differnt wattage.
Each contact goes to one filament, the reurn is the base.
low wattage filament - low
high wattage filament - medium
both filaments - high.
