I don't know anything about logwatch. But if your premise is correct, and logs are being collected onto a central machine and then processed and ending up in the central machine's /var/log/syslog file, that would be equivalent to having syslog() and syslogd set up for remote logging -- just with extra steps and delays. This would certainly explain how sshd startup complaints from machine X are ending up in the /var/log/syslog file on machine Y. You'd think the OP would know about this, if they did in fact set up such a thing.
