My question has been answered as it now appears that some airlines are teaching the power off stall with power on recovery while keeping a high AOA to minimize altitude loss.
I don't know about airlines, but I know that that was not a Boeing manoeuvre for "stall recovery" (an upset recovery due to loss of control), but for "approach to stall" where control is still maintained.
For an actual stall, the advice is and was to maintaining a nose down attitude until the stick shaker stops. Recently, the stall recovery manoeuvre was changed to also incorporate stall to approach so that in either case the first action should be to select a lower nose attitude.
