Yes, this is the inteded behavior, though some consider this a design
bug. Network config is persisted on each host, and Engine do not
automatically applies its own definitions ona re-provisioned host,
however, we have

    1194297     [RFE] Allow to synchronize all networks on an
    out-of-sync host

in the works, which would make life easier in such conditions.
