PVS-Studio warning V519 for TPP

void ASAPCGIParser::writeProteinRatio(ostream& os,
  proDataStrct* pro_ratio, const char* name)
{
  ...
  pvalue = (double)norm_->normalize(adj_inv_ratio);  <<<---

  double tmp[2];
  tmp[0] = adj_inv_ratio[0];
  tmp[1] = adj_inv_ratio[1];
  adj_inv_ratio[0] = 1/ tmp[0];
  adj_inv_ratio[1] = tmp[1]/(tmp[0]*tmp[0]);

  pvalue = (double)norm_->normalize(adjratio);       <<<---
  ...
}

This suspicious code was found in TPP project by PVS-Studio static code analyzer.
Warning message is:
V519 The 'pvalue' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 205, 214. tpplib asapcgiparser.cxx 214 (....)
