Three things:-
1) Pilot clearly said I didn't do it.
2) Report talks about the second switch being turned off in a second.
3) Known advisory on switches getting flipped.
If you see these three together, it becomes easy to deduce that based on point 2, switch was not human induced as the actions required take more than a second.
Next the third point, advisory was for this exact scenario which played out, though rare but still it shouldn't have been just an advisory, but more than that.
