Ah, who knows...

The spoilers are hydraulically driven, and sometimes cable actuated. Unless the several hydraulic systems driving the spoiler boards have failed, they are driven closed and open by 3000psi of hydraulic pressure. Failed hydraulics, and high angle of attack MIGHT get them to float, but they all would be floating.
Once again, this is probably a mis-rigged board, powered up out of stow slightly, making the aileron compensate.
We know from the report that the opposite wing had no such deflections of either kind.
