I agree that using a unix socket is better than using a tcp socket and can support updating the ordering.
I also see no reason not to update the example to point at the newer PHP socket location. However, that other line is an example of connecting to a TCP socket and I do not feel that it should be removed. I see (with painful frequency) users uncommenting that line in order to use apache to serve php (or worse). As much as I'd prefer people deploy more robust/sane setups, I really don't want to field all of the extra questions because the line went missing.
