Overspeed vs Stall: why not both of them ?

Hey Will. Can't a severe overspeed end up into a stall ? (high speed stall/mach buffet).
To me, there is no contradiction between an initial overspeed and a stall (or even two: a stall by exiting the upper limit at high altitude during the overspeed, then, after a nearly successfull recovery/flight point back again within the envelope, exiting the lower limit of the flight envelope due to an overcorrection at low altitude).

PS) Has NTSB scheduled any report of its investigations ?
