PVS-Studio warning V547 for WebPagetest

bool
Reader::readArray( Token &tokenStart )
{
  ....
  bool badTokenType = ( token.type_ == tokenArraySeparator &&
                        token.type_ == tokenArrayEnd );
  if ( !ok  ||  badTokenType )
  {
    ....
}

This is what should have been written here: token.type_ != tokenArraySeparator && token.type_ != tokenArrayEnd

This suspicious code was found in WebPagetest project by PVS-Studio static code analyzer.
Warning message is:
V547 Expression is always false. Probably the '||' operator should be used here. json_reader.cpp 566
