There is already a form of this at work in the game as the AI will claim all systems adjacent to one in which it has colonies. The problem the Baron was alluding to is the lack of memory from turn to turn. EU being a RTS has more continuity since it doesn't have an "end of turn". Using your example, SE4's problem is akin to in EU of Russia sending an army against Poland and then at some point forgetting it was at war with it and then sending it against the Khanates. Whatever decisions are made on turn x are not carried through to turns y+. So frequently the AI will decide to launch a massive invasion to reclaim a system to only have the fleet arrive and "forget" why it was sent, leaving without doing anything. Any particular course of action that cannot be completed in a single turn are subject to being over-ruled in later turns, even when no compelling reason can be shown for the change.
