PVS-Studio warning V519 for Crystalspace

csVector3 sampleDistanceReal;

void csSimpleSampler::CachePositions ()
{
  ...
  // Compute distance between sample points
  sampleDistanceReal = (resx == 1) ? 0 :
    (maxCorner.x-minCorner.x)/(float)(resx-1);
  sampleDistanceReal = (resz == 1) ? 0 :
    (maxCorner.z-minCorner.z)/(float)(resz-1);
  ...
}

Most likely this is what should be written here: sampleDistanceReal.x = ...; sampleDistanceReal.z = ...;

This suspicious code was found in Crystalspace project by PVS-Studio static code analyzer.
Warning message is:
V519 The 'sampleDistanceReal' object is assigned values twice successively. Perhaps this is a mistake. plgsimpleformer simpleformer.cpp 642
