It is based upon the fact that reverse, braking and spoilers all serve to promote an effective weight-shift towards the nose
Errr, no they dont. Reverse and spoilers can act in opposite directions in terms of pitch moment. They certainly do on the A320 and B747. I don't know if the author has ever flown a high performance jet with an efficient wing but pulling back on the stick immediately after landing
will put the nose back in the air, not to mention robbing you of all nose wheel steering.
The whole point of the article seems to be that it's better to get the weight on the wheels ASAP so the autobrakes can do their job. That is already the technique recommended by Airbus and Boeing. Once the autobrakes are active pulling back on the stick will make no difference to the braking distance as most autobrakes command a deceleration
rate. If the aircraft isn't slowing they'll just put the brakes on harder. If you compare the performance of the brakes in the RTO setting compared to a normal landing setting you'll see theres a lot of spare left. I believe in the Air France case at Toronto even with full braking and reverse they wouldn't have stopped anyway because they'd landed about 2000m down the runway!
