PVS-Studio warning V501 for Ultimate ToolBox

void COXFrameWndSizeDock::TileDockedBars(
  DWORD dwDockStyle)
{
  ...
  if (pDock != NULL &&
      (pDock->m_dwStyle &&
       dwDockStyle == dwDockStyle))
  ...
}

Probably some other expression should be written instead of "dwDockStyle == dwDockStyle".

This suspicious code was found in Ultimate ToolBox project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions to the left and to the right of the '==' operator: dwDockStyle == dwDockStyle UT oxframewnddock.cpp 190
