Short answer, yes. Longer answer. I have a setup with two nodes with two interfaces, one is connected via a switch to the other node and one is a back-to-back link for DRBD replication. In Corosync I have two rings, one that goes via the switch and one via the back-to-back link (rrp_mode: active). With rrp_mode: passive it should work the way you mentioned.
