No, that was possible with ipchains where logging was not a target, but
an option. Iptables does not allow multiple targets, i.e. it does not
allow multiple -j flags. Hence two separate rules is how it must be
done.

You can also match only once and then jump to a user-defined chain,
which does a simple catch-all LOG/REJECT, e.g.

  -N logreject
  -A logreject -j LOG
  -A logreject -j REJECT

  -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 0:1023 -j logreject
