What does the "Enable the scheduled change conflict checker" check box do?

[Cameron17]

In the "Customization Properties for the detection of Change conflicts" page for Change Management, what does the "Enable the scheduled change conflict checker" check box do? I can't find any difference with conflict detection when the box is checked or unchecked.
