No. "Over" meaning "flying over at the time". If I meant what you imply, I would have said "killed in a dispute over Crooked Mountain".

The Redmountain Hills and Crooked Mountain are two distinct and unrelated places. Note that Xykon refers to "drawing Durokan out" from his hiding place in the Redmountain Hills. Also, in the picture showing their duel, the sky is a normal blue rather than the red sky seen above the Redmountain Hills.
