In ASA and Fed, the runners are returned to the base occupied at the time of the interference - this move is considered interference. In NCAA, the runners are returned to the base occupied at the time of the pitch. It is entirely possible and likely that both of your runners had obtained the advance base prior to the batter-runner stepping backward toward home - since they are likely breaking on the pitch.
