I didn't say he was in the Bayesian camp, I said he had the Bayesian insight that probability is in the mind.

In the final quote he is simply saying that mathematical statements of probability merely summarize our state of knowledge; they do not add anything to it other than putting it in a more useful form. I don't see how this would be interpreted as going against subjectivism, especially when he clearly refers to probabilities being expressions of our ignorance.
