Perfectly was a poor choice of words. I would expect there to be much more variation in the combinations of beliefs that people hold than is observed. People who favor more aid to the poor are likely to also be pro choice. People who are pro war are likely to be pro life (these are true for US politics at least).
It is not obvious why these particular beliefs should be connected. I think you could make a convincing “just so” story for the sets of beliefs as they are and for their opposites.
edit: in a world where people thought through each of their beliefs independently I would expect the ratio of numBelieves(pro war, pro life) : numBelieves(pro war, pro choice) to be a lot closer to 1 than we observe.
