RWA,
I think the word choice in the description is not as clear as it could be. Flaps not in landing configuration does not necessarily mean stowed. From a flaps full landing configuration to go-around would mean repositioning to flaps 3. From flaps 3 landing configuration to flaps 2 for go-around. Flaps full and 3 are considered normal landing configurations.
The spoiler panel deployed appears to be panel 5. Panels 2-5 are used in flight to varying degrees. It is difficult to tell if the position of the left aileron is consistent with slight roll being commanded or just normal aileron droop with flaps deployed.
