Will a zinc rod carrying a current attract or repel a copper rod carrying a current in

"In zinc however, conduction is dominated by the motion of positive charge carriers. Electrons in zinc that are excited from the valence band leave holes, which are vacancies (i.e., unfilled levels) that behave like positive charge carriers. The motion of these holes accounts for most of the conduction of electricity in zinc."
I though hole flow and electron flow were always equivalent. They teach hole flow in the military due to so many being dug.
