Code:
$ man logger

LOGGER(1)                 BSD General Commands Manual                LOGGER(1)

NAME
     logger -- a shell command interface to the syslog(3) system log module

SYNOPSIS
     logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]

DESCRIPTION
     Logger makes entries in the system log.  It provides a shell command
     interface to the syslog(3) system log module.

...

So the 'logger' command does not run the command, just writes the text it was given into the system log file.

The logger command is adding an entry into your system logger (/var/log/messages or /var/adm/messages) that the command is starting:

postback Starting /opt/local/bin/backup-report

The second line is actually starting the command.
