What I've always assumed it does is take a single device (like my mouse) and split the X coord to one joystick port, and Y coord to other joystick port, and then using both the horizontal and vertical inputs of each port, give you 64x64 (4096) discreet positions instead of the normal 0-63 for each axis.

No. The CPU watches something (I think it's capacitors charging) to
determine the coordinates, and the larger the coordinate value, the
longer it takes to read it, so you learn quickly that when you aren't
doing anything with the mouse, move it to the top left corner of the screen.
