Am I doing something wrong?

I don't have an solution to get Lily to do what you want, but it appears that the \ShiftOn and related commands only work when the two voices have the stems pointing in the same direction. From the NR:

The \shiftOn command allows (but does not force) the notes in a voice to be shifted. When \shiftOn is applied to a voice, a note or chord in that voice is shifted only if its stem would otherwise collide with a stem from another voice, and only if the colliding stems point in the same direction. 

Sorry to not be of more help. Maybe someone else has a solution?
