PVS-Studio warning V519 for ReactOS

HPALETTE CardWindow::CreateCardPalette()
{
  ...
  //include button text colours
  cols[0] = RGB(0, 0, 0);
  cols[1] = RGB(255, 255, 255);

  //include the base background colour
  cols[1] = crBackgnd;

  //include the standard button colours...
  cols[3] = CardButton::GetHighlight(crBackgnd);
  cols[4] = CardButton::GetShadow(crBackgnd);
  cols[5] = CardButton::GetFace(crBackgnd);
  ...
}

Most likely this is what should be written here: cols[2] = crBackgnd;

This suspicious code was found in ReactOS project by PVS-Studio static code analyzer.
Warning message is:
V519 The 'cols [1]' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 716, 719. cardlib cardwindow.cpp 719
