Yes, that is exactly what happened. I clicked the holo-terminal at 47 and it started a conversation with Darth Marr, then instantly flew me to Makebb where Marr spoilered the ending of my 1-50 storyline. If you don't want to be spoiled, DO NOT CLICK THE HOLOTERMINAL after level 45. Make sure you pick up all your storyline quests before you reach that level.
