Learning something is different from practised usage. What you have provided is not a counter example at all, it's evidence that once you have learned to read, you (usually) have deeper structures that can adapt to and survive perturbations. The ability of adults who can read to be able to decode examples such as yours might be behind the drive to use the "guess and move on" method being discussed. My personal experience of working with a wide range of people is that many of them see the words, say the words, and move on without actually internalising what they've said. The derogatory term "barking at print" comes to mind. I've seen it, and I find it sad that there are otherwise intelligent and capable people who fundamentally can't read.
