Because you didn't specify in this email where /home is mounted, I can
only guess /home is actually a symlink to /usr/home


Because /usr/home is under the /usr mountpoint and you specified
'-alldirs' in the exports, any dir under /usr can be mounted.

NFS exports work ONLY on mountpoints, they do not work under child
directories unless -alldirs is specified and then any dir under that
mountpoint can be mounted.
