I'm not at my editing computer but as I recall you can return to a single track by right-clicking on the track header and selecting the appropriate command.

Remember that "In expanded edit mode, a red bracket is displayed to indicate which event edge will be trimmed, and the track is displayed in an A/B roll: events before the edit point are displayed in the A roll and subsequent events are displayed on the B roll. Additional frames available for editing are shown on the other side of the edit point. --- The Video Preview window displays a split-screen preview so you can monitor frames on both sides of the edit point."
