Postfix mail flow confusion

i have question about the flow that an incoming email message goes trough the Postfix processes. According to Postfix documentation here: https://www.postfix.org/MILTER_README.html it seems to be that the message received via the smtpd daemon will first be processed by the configured milters and after that by the cleanup process before placed inside the queue. So - the path should be smtpd -> milters -> cleanup -> queue ... Looks fine, however i wonder why my log file looks like this - as you can see, the **cleanup** process log line comes **BEFORE** the lines written by the milters (**opendkim,opendmarc**)

It looks like the milters are called asynchronously?
