Perhaps if he was practicing minimum controllable airspeed when the shear occurred....even then recovery would be a non-event.
A 2g load increases the stall speed by ~40%. It's harder to apply a sustained 2g load than you realize, a momentary event doesn't count. So you can fly a 172 at 75 kts, which is pretty slow, apply a 2g load and it won't stall because it's still within the flying envelope.
