They are somewhat redundant. They get everything at once, unlike update hook.

The old interface is adequate to do the same thing if you arrange them so that update hook notes which refs (with what old sha1 value it had) were asked to be updated, and make your post-update hook (which gets the names of refs) notice if some of them failed and from what ref a successful update happened. But getting everything at once is sometimes easier to work with.
