I think it means becoming more truely evil and actually having alternative end gameplay.
In KOTOR, the end of your game depends on whether you're evil or good, and you play that ending.
In AO/AE/MO, out actions didn't technically change the outcome of the game. The levels were still exactly the same, but they did change the outcome of the cutscenes.
Perhaps Stranger won't have multiple ending cutscenes, I'm just speculating.
