What does "in areas" distinguish in Atlas passives?

I've been getting some Atlas passives from Maven. Almost all passives contain the qualifier "in areas". What does this mean exactly? I have the following guesses:

• In maps only
• Not campaign or boss fights, like Maven herself
• Only that section of the Atlas, like Heawark Hamlet
• Maps that have the corresponding master mission active

It means the quadrant that the passive tree belongs to. For instance, take Lira Arthain for example. If you were to take Distinguished Demolitionist, you gain 35% increased Explosive Radius and 20% increased number of Explosives in maps that belong to Lira Arthain.
