Downward deflection on left inboard aileron = right roll.
Tsk, tsk, YOU should now better!
Although, I haven't a clue what the explanation is either!
All I know is that in cruise (or flaps up) the outboard ailerons & spoilers are locked, and the inboard ailerons/spoilers work in concert to control roll.
The only thing that comes to mind is maybe the AP is compensating for a nasty crosswind (crabbing w/ right aileron + left rudder), and the spoiler is countering the rudder-induced yaw? Still that looks like a lot of deflection for trim. Are you sure you weren't in a gradual right turn? Even the wing vs. horizon in the picture kinda looks that way.
Also, since the spoiler is only slightly deflected, another explanation may be that it's cable needs to be re-tensioned and the extreme low pressure on the top side of the wing is "sucking" it up into airstream.
Ah, who knows...
