Regarding stall warning and stall, the differences are indeed not that big.
In clean configuration, level flight at low altitude with idle thrust, Jaques Rosay would have decelerated at about 1.2 to 1.3 kt/sec.
AF447 decelerated at about 1.7 to 1.8 kt/sec which is somewhat faster, but OTOH the margin between stall warning and stall is greater.
The point that Rosay is making, that selecting TOGA in response to stall warning doesn't keep you out of a stall, applies equally to AF447.
