Lets be real on one thing though. Kimmie Meissner was NEVER going to get the same score she got at Worlds even for the exact same performance at the Olympics. Worlds was a weak field with Arakawa and Slutskaya out (in addition to Asada, Kim, Ando, and Kwan, not that Ando or Kwan were even real contenders that year but still). Olympics was still a decent field with all the main contenders outside Asada (Kim and Kwan were minor contenders at that point at best) present, even though it turned into a splatter, but either way Meissner was never supposed to be a player in the Turin field, but the Worlds field was depleted enough, that after a strong Olympics and continuing her consistent skating, she was perceived a factor and there were limited options of viable contenders for the judges to draw upon by then anyway. She skated right after a really poor performance by Cohen, and the judges were probably terrified at the prospect of Cohen winning Worlds with that performance, as Suguri was no certainty to beat even a splatty Cohen, so went a bit too crazy on Meissner's scores, which on a side note led to some inflated PCS for her for atleast a couple more years, even though her presentation would continue to improve. Furthermore the judges scoring at Worlds was far more generous for the ladies than at the Games were they were very tight with PCS and especialy GOE. Cohen and Suguri both bested their Olympic SP scores for much worse performances with a badly two footed combo each. Suguri far bested her Olympic LP score with really a no better performance. Lastly by the Worlds LP Meissner had gained the judges respect after several events and a number of straight performances of consistent skating, whereas before the Olympics she had not earned that respect yet. Her PCS even in the qualifying and short program phases of Worlds had started to rise. The PCS she got at Worlds (which many thought were ridiculously high even with how well she skated) was never ever happening at the Turin Olympics, no matter how well she skated. I would see her getting 120 max which would still leave her out of the medals overall.
I doubt the Japanese factored in any worry Meissner was going to bump them off the podium before Arakawa and Suguri skated, they were pretty much certain to get atleast one medal at that point, unless both Arakawa and Suguri really imploded. Arakawa might have worried that she herself with a couple falls could be off the podium in favor of all of Cohen, Slutskaya, and Suguri, especialy as Sasha's 2nd fall wasnt recorded as an actual fall as it should have been, hence why she played it safe to secure a medal.
