Dmoz seems to be based more on trust than anything else. Editors often work together placing sites, re-organizing the directory. The checks and balances come into play when someone steps out of line. In every single category numerous editors have the capability to make changes. Top level editors can edit and correct anything anywhere. One only makes it to the top or gains additional categories areter demonstrating an increased proficiency, and adherance to guidelines over time.
