This reports the completion state of just this one stage (for example pending, in-progress, skipped, failed, or completed) as opposed to the FSM-level status covering the whole workflow. For a scheduled export-policy job (for example a nightly tech-support or full-state configuration backup) defined for the UCS domain, this is the field that pinpoints exactly which step of pushing a configuration or diagnostic bundle out to a remote TFTP/FTP/SCP/SFTP server on the schedule the policy defines is the one currently blocking progress. A stage sitting at 'failed' while later stages read 'pending' tells an admin the whole job is blocked right there.
