PVS-Studio warning V668 for ITK

#define ITK_NULLPTR  nullptr

void LinearSystemWrapperVNL::InitializeMatrix(....)
{
  if( m_Matrices == ITK_NULLPTR )
  {
    m_Matrices = new MatrixHolder(m_NumberOfMatrices);
    if( m_Matrices == ITK_NULLPTR )
    {
      itkGenericExceptionMacro(....);
    }
  }
  ....
}

This suspicious code was found in ITK project by PVS-Studio static code analyzer.
Warning message is:
V668 There is no sense in testing the 'm_Matrices' pointer against null, as the memory was allocated using the 'new' operator. The exception will be generated in the case of memory allocation error. itkfemlinearsystemwrappervnl.cxx 33
