I did read your memory Alpha link and then I read the Memory Alpha Link for Endgame where Alice admitted that she read the previous Borg Queen Voyager scripts in preparation of this role and resuming the character.
Alice thinks that the characters are the same and no one saw fit to change her mind.
Ideas behind the scenes are fluid.
I'm not saying that you're wrong, I'm only saying that they're inconsistent.
When they did their press for Dark Frontier it's possible that they hadn't started writing Endgame yet.
