No, she was not. The two story lines are incompatible: where one occurs, the other does not. Leia could not possibly have been referring to the DLC that continues from the dark side ending to the first game because the entirety of TFU2
continues from the light side ending to the first game (but branching off from the dark side ending to the second game).
Leia means that Luke was killed on Hoth in this second apocryphal story line.
