my QRH says that a FAC 1+2 reset should only be done on the ground. Seems pretty clear, to reset in flight with the CB's means this crew was in unknown territory and effectively became test pilots. The interesting thing will be WHY this course of action was taken, if it was the result of a 'last ditch effort' to save the plane then fair enough. If it was a non-standard reset for something minor like a WINDSHEAR detection fault then all these people have been killed for no good reason. Only the report will reveal the answer.
