I think that was the chain of command breakdown given in "Arise Serpentor, Arise!" if that means anything. Someone said that as a way of explaining who Hawk and Beachhead were supposed to be, and I guess, why Joes would be following their orders that season instead of Flint and Duke (who got drastically reduced screen time since their toys were no longer being produced).
I think that was also seen on a computer Serpentor accesses in the episode "The Most Dangerous Thing in the World"
1. Hawk
2. Duke
3. Flint
4. Beachhead
