It keeps a copy of the repository locally. This doesn't help much for
saving space when you've got only one working copy (it might help a bit:
  svn repositories are compressed; on the other hand, you've got copies
of things even if you don't have working copies). However, if you've
got several working copies from the same repository (e.g. trunk and
branch checkouts), you may see substantial space savings.

The links you mention don't suggest this as a possibility, but I think
getting svn to keep local copies of the whole respository has other
advantages, in that all past history of a file is kept locally, not just
HEAD. This would make working offline a lot more productive. I don't
think this implies dealing with any of the other issues svk addresses
(e.g. you don't need to allow offline commits).
