It's not needed but it's a safety net in case whatever is sending the
passive checks stops doing so. Nagios would happily continue to report
the last check it received before the submission process died forever.
Freshness checking allows nagios to recognize that it hasn't seen any
recent results for that host in some configurable time and runs the
hosts check_command to be pro-active. The documentation covers some
scenarios about what that check_command can/should be.
