That's correct.  This is how the SNMP protocol is designed.
Please see the FAQ entry
    Why doesn't the agent respond?
         http://www.net-snmp.org/wiki/index.php/FAQ:Applications_04

This is basically due to the access control settings of the agent.
It will refuse to talk to an unauthorised client.

That's because there's nothing to respond.  If you direct a request
to a host/port where there's nothing listening, then of course you
won't get a response!
