So it does. I think they mean unused in a mono situation.

(I did check with two guitar leads and a stereo plug. Fun thing is if I actually wanted to use it as a stereo socket it would be useless. Only two pins tracked through to the stereo plug.)

I'll just wire it such as makes sense from what my meter says.
