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.
