I’m simply giving my comments but others please correct me if this is not correct.
For Scenario 1 - your leader node0 is offline - and your quorum is now not stable. So if a leader goes offline it's not certain who will take over. So that's why 3 is recommended as a minimum, however not the best number to deploy in production. For Scenario 2 - Your leader node0 is online. So even if node 1 or 2 is stopped, the consumers can get the message from leaders, not followers. So this is not unexpected.
