Its an odd post in a way as if the mount was so accurate that such a perfect polar alignment were achieved then it would likely be largely free of backlash etc.
T-point model shoots for the refracted pole and you input current altitude and atmospheric pressure. But as Peter says if it shifts somewhat with pressure and temp I guess we are really only after very very close in the order of 30 arc seconds or so.
I can only say I have never seen the effect mentioned but I have only been that perfect in my polar alignment with the PME which doesn't bounce around anyway.
But if a mount does exhibit bounce and oscillations like this guys apparently has then perhaps it is good advice.
Greg.
