I'm not sure that's true, Phil. If a star's ecliptic faces us edge-on, then we will see a wobble only along one (the ecliptic's) axis. If the ecliptic is at maximum away from us (bad description! I mean it's pole is facing us so we are looking down at the system.) then the wobble will describe a circle.

Given sufficiently sensitive instrumentation, you could examine the ratio between the wobble along one axis with the wobble along the other axis and figure out the degrees of inclination.
