My understanding is the base to final turn scenario in the stalling exercises, is not to experience a stall and the consequences, but to teach recognition of the approach to the stall and an immediate reduction of angle of attack and a controlled recovery.
Anyone who actually stalls in this configuration at 5-700 ft would be lucky to recover before hitting the ground. So in this case, lets emphasise the recognition of the approaching stall and a safe recovery. If someone wants to see why, then go high and find out.
