The information conveyed by radio light is spread widely enough so that you can estimate the information it is carrying from just detecting it at two widely spread detectors – and then superimposing that data. The fine detailed information contained in visible light is just too complex to allow this."

I think the author must have seriously misinterpreted something that an astronomer said or is just winging it without really knowing what he's talking about. Or I'm just hopelessly confused.

I'd guess that it's a combination of both.
