Pretty much. Penrose, despite being generally brilliant, is not an expert in neuroscience. QM explanations seem like hand waving or saying "we don't really know, and since I know a lot about QM, that must be the reason". It's almost avoiding investigation into the hard problems of neurobiology to find the real, physical processes that bring about human cognition.
