I think it's plausible since doctors tend to have human cognitive biases and miss things. People tend to fixate on patterns they're most familiar with.
Meanwhile with human doctors, every one of them is a unique person with a completely different set of biases. In my experience, getting a correct diagnosis or treatment plan often involves trying multiple doctors, because many of them will jump to a common diagnosis even if the symptoms don't line up and the treatment doesn't actually help.
