Except that I don't think there's a subtle secondary message. The straightforward interpretation is probably correct and I don't think looking for a deeper meaning is going lead to extra insight.

I agree with this. (Your use of "except" confuses me by making it seem as if you think I thought the opposite of those two sentences. Edit: This jumped out as important because the difference between stating beliefs about optimal decision policy and stating beliefs about what decision policies others are engaging in is a big difference.)
