Crash One
Yes you are correct and the Glider is a good example of how power can be misleading in stall recovery.
Any aircraft will recover From a stall including the jet I fly by pitch alone and tapping into potential energy inherent in the airframe.
We are looking at 2 angles ! Reducing the AOA and gaining back a flow of air over the wings so they fly again and doing that with as little altitude loss as possible.
I brought in that recovery can be type specific! Some will pitch up with power application requiring more counter pitch down by the pilot while others will pitch down with power application requiring less
But point taken
