Having endings that doesn't necessarily have meaning for the sequel is actually a -good- thing, if it means you have more endings.
There's nothing better than getting an ending based on what happened in the game, and the choices you made,
even if those choices aren't taken to account in the sequel.
Few games let player-choice move from game to game (:o imagine the crazy branching stories the writers must make!) , though when it happens?
It's an awesome thing to behold, loved that about the Mass Effect games (and to some extent Dragon Age 1 - 3)
...But ya ^^ Agree it'd be silly if Loren wasn't around for Loren 2
