Figuring out what rules are overridden and when can be challenging. My general approach is what are the minimum number of rules that need to be ignored in order for the card to work.
So, in the case of
Consume Outpost the normal requirements for building an outpost could all apply, a Borg player could capture and Brainwash an opponent's Fed ENGINEER to build the outpost. However, the designer's didn't want you to have to do that, hence the ability to ignore the ENIGINEER requirement. And since the Outpost does have to match an affiliation icon of the mission, the download has to come from outside the game since a Borg player may not have a Fed outpost in there deck.
With
Population 9 Billion - All Borg, there are 2 rules that need to be overcome. First that outposts may not be built at a Homeworld and second the location requirements of any particular Borg outpost you wish to build. So, in order for that aspect of the card to mean anything, it has to be overriding those two requirements.
Is that a clear system for overriding the rules? Not entirely, but it was the best Decipher could do trying to fit the text into small spaces and not issue errata, something they were loathe to do. Could the CC issue errata to every card which overrides a rule to specifically say which rule is being overridden on the card? Perhaps, but finding those cards, working out the correct wording that will fit the current card templates or creating new templates to accommodate more wording, and any possibly required rules adjustments would take time and resources away from creating new cards. Is mass errata for clarification something some people would like to see? Probably, but I get the impression that it is not something most people feel is needed. To be fair, the last batch of errata was solely for the purposes to update old cards to modern wording, and we've been told to expect more in the future. So, clearly there is an understanding that such changes have value.
