Must have been a very old version of dhcpd, or a bug in the parser :)

Split it into two host statements. Note that the host label must be
unique, so something like this will work:

        host benz-old {
                option host-name "benz";
                hardware ethernet 00:16:36:85:B4:C9;
                fixed-address 192.168.2.73;
        }
        host benz {
                option host-name "benz";
                hardware ethernet 00:18:DE:30:51:F1;
                fixed-address 192.168.2.73;
        }
