That's how it differs for the PLAYERS, not how it differs for the DM.One is just a battle arena with no exploration, the other has distinct areas thst need to be explored and wrong tracks to go down. Seems straightforward and consistent to me.
EDIT: The DM needs to know what's in those three Keyed locations (plus the "maze") on the first map, and what's in the four rooms on the second. And keep which is which straight. They're both simple (in that they've got four parts each).
