This list is much too broad -- Google is NOT universally blocked in China.
Rather, they look for forbidden keywords in queries and block results.
See my other comment here. The list was made not to inform what is blocked, but to configure a piece of circumvention software. It's easier for us in the early days to just proxy all of google from a friend's computer than to just send particular queries. The source list from autoproxy is much better with the queries and parts of google that are blocked.
