Neither associated it with a pressurisation problem. Knowing that takeoff configuration couldn’t be the cause, they assumed that the problem was the horn itself and switched it off, only realising their mistake when the oxygen masks dropped in the cabin'.
In which case should the masks have dropped in the cabin on flight 522.
The article also doesn't say how widely it was known that the same horn could mean two different things.

Are the masks in the cabin on the same system as those in the cockpit.
Even I have listened to enough Safety Briefs to link that with de pressurisation.
