It invalidates the updates_cache, sure.

Erm, I don't follow. The cache is invalidated so the next GetUpdates
call actually runs the backend->get_updates function. By invalidating we
just say "this probably isn't true anymore".

Do you mean that you don't want to invalidate the updates cache if there
are no packages updates with UpdateSystem?
