Thanks for reporting this bug. The confusion between the terms Update and upgrade is also discussed in bug #734026, so I am marking this as a duplicate of that bug. Feel free to comment there. As a summary from there, to have a consistent terminology, it would be best to have update used for updating packages on the same version of the OS, and use upgrades only for distribution upgrades to be able to differentiate between the two actions as the two are very different use-cases, with major differences in the outcome and possible dangers, whereas updates as you are using it (update repo/sources list) does not mean anything by itself, it is only a part of the process, which does not make any sense alone. See the discussion on the other bugs thread for the reasons.
