The paragraph I quoted was mixed up to a certain extent. That paragraph was actually referring to the energy contained in e and B fields located outside the conductor. The Poynting vector energy density points in the direction of free electron motion. Current and voltage are scalar quantities so they do not travel or have any direction. What does travel and have direction are the free electrons, the moving charges. As you said, they move one direction in one wire while moving simultaneously in the other wire in the opposite direction.
