I think that using localhost on each node will lead to split-brain.
With the backup volfile setting taking care of failover, I don't think
mounting at localhost buys you anything, anyway. Gluster already
handles spreading out the load among the hosts on its own, when you're
using the native gluster mounts (vs nfs, where you are accessing
through the specified mount point).
