Wait for Host & Continue Without Host

Can someone please explain the purpose or meaning of these meeting settings “Wait for Host & Continue Without Host”?

Wait for Host: Set conference to start with or without a host. Off (default) allows conference to start when the first participant arrives. On - x minute(s) places participants on hold for selected time. If the host does not join within that time, participants will be disconnected.

Continue without a host: Set conference to continue or terminate without host. On (default) allows conference to continue after host disconnects. On - x minute(s) allows conference to continue for selected time after host disconnects.
