Absolutely it depends on aircraft type. However I believe the intent of the article in flight safety was referring to your normal GA trainer aircraft which doesn’t have a lot of those aerodynamic peculiarities. Even so, most GA aircraft will stall inboard first due to things like washout. You can use aileron right up to the stall. But once it is in the stall, no aileron. Also at the light buffet the onboard section of the wing isn’t stalled either, hence why the buffet is a great warning that you are approaching the critical angle.
