I'm not sure what you mean by bi-directional flow, but I think in general it refers to the fact that under different circumstances the direction of power flow can be different. MATPOWER's runpf can tell you which direction the power is flowing for a given operating point, but not whether the operating points observed under normal conditions vary sufficiently to cause the direction of that flow to switch.
