Just have a look at this document, maybe it clarifies a few things:

The graphs presented in the accident report aren't what the ailerons/spoilers do when you input roll commands to the EFCS. These are (most likely) the "kinematics" blocks presented in the paper (the picture where the overall control loop is shown). You are "flying a control loop".
