Not an expert on the 747, but I'll propose the following for thought: The downward-deflected control surface is deflected downwards to increase camber (and lift) on the left wing, trimming for wings-level versus a left-wing-low condition in an untrimmed condition. The upward-deflected surface (spoiler) is deflected upwards in lieu of rudder trim to trim YAW - i.e. dragging the left wing back and trimming against a nose-right untrimmed condition.

Possible? Dunno.
