Failover of active NFS mounts isn't something that autofs can do. When I say that I don't mean it hasn't been implemented, I mean, as far as I can see, it's not possible for autofs to do it. I've thought about quite a bit and I just can't see a way to implement it. Once autofs has selected a server and performed the mount it has no knowledge of what is happening in the mount itself. All that autofs could do (if it was implemented in the NFS client) is to pass an ordered list of servers to mount so it can then pass that to the kernel. This is essentially what the Solaris automount does. This has to be supported in the kernel NFS client and it's not.
