disputed origin

Possibly from the split tongue of a snake, an anatomical feature associated with the capacity to project two different messages. The phrase remains of uncertain origin, resting upon the observation that a serpent possesses a bifurcated organ which suggests, by way of simple biological metaphor, the act of saying one thing while simultaneously meaning another.
