It's interesting; I read these sources completely differently. The first doesn't enumerate any privileges of the title. For example, it doesn't mention voting rights afforded to liverymen in London's traditional elections (the titles are basically sinecures, but they do come with money and a certain amount of prestige so there's arguably a point to them). The quote about driving sheep being largely symbolic, I read that as saying "technically you can do this but hardly anyone exercises the right because there's no economic benefit". No shepherds would want or need to bring sheep to market in that particular way. No flocks of sheep are even likely nearby. So in that sense the benefits are all relatively silly and unusual, not necessarily practical.
