You are not reading what I have written.
I would fully understand the procedure if in fact it had the effect of increasing pressure on the nose wheel.
I don't think it does for the reasons I have stated twice.
Particularly in the case of a tailwind, where if there is any effect of stick down it would be to release pressure on the nose wheel for the critical early stage of the acceleration. Think about what reverse flow over a wing does! If you push forward you are increasing the downward force it is producing until flow over the tail is in the correct sense.
Fortunately, I don't think this is a problem because the forces created over a wing at low speed are negligible hence relying on nose wheel steering until some decent air flow is produced by forward acceleration.

That would be a good justification if true. Do you reckon that there is actually some "blown" effect that high up?
