PVS-Studio warning V524 for Nmap

class NpingTimer {
  ...
  int start();
  int stop();
  ...
};

int NpingStats::startRuntime(){
  this->run_timer.start();
  return OP_SUCCESS;
}

int NpingStats::stopRuntime(){
  this->run_timer.start();
  return OP_SUCCESS;
}

Most likely this is what should be written in stopRuntime: this->run_timer.stop();

This suspicious code was found in Nmap project by PVS-Studio static code analyzer.
Warning message is:
V524 It is odd that the body of 'stopRuntime' function is fully equivalent to the body of 'startRuntime' function (stats.cc, line 274). nping stats.cc 280
