Well in the murder-suicide scenario it makes sense for the culprit to turn them off as quickly as possible. The longer time to turn them on could plausibly be a struggle or simply needing to fly the plane while reaching for each switch individually.
Assuming the person trying to kill themselves and a plane load of people would respond in an expected way to inquiry is also just a mistake.
It's not a rational decision, so there's no reason to expect rational decision making or explanation on the output.
Too many are willing to accept the Bart Simpson excuse of "I didn't do it" at face value.
