config-sync documentation contradictory - from-group and to-group

The tmsh documentation for 'run config-sync' states

   run config-sync from-group /Common/my_dg

   Updates the configurations on the remote devices in the device group
   Common/my_dg with the configuration on the local device. If the local
   device does not have the newest configuration, then the configuration
   synchronization does nothing.

and

   from-group
        Updates the configuration of the local device with the configura-
        tion of the remote device in the specified device group that has
        the newest configuration. If the local device already has the
        newest configuration, then the configuration synchronization does
        nothing. This option is mutually exclusive of the to-group and
        recover-sync options.

One seems to say copy the remote to the local, the other says copy local to remote. Am I missing something here, or is this contradictory? Either way, what do I use to synchronise the config from the device I am logged on to, to the other devices in the group?
