I think the problem with this reasoning is that both branches got only part of the original. Apache got the trademark and the domain name, but The Document Foundation got the community. So ApacheOffice sees a lot of downloads from users that don't know yet that there is now a more capable branch of the original out there. LibrOffice sees a lot of new development and features, sharing the development cost with a large developer base. Sharing the trademark and downloads/updates sites to give the user choice seems beneficial for both. That way it is also more clear which fork/branch users prefer and hopefully will show how to push a shared vision forward around free software office suites and the ODF standard.
