You are correct. Still messed up though if you are using another
browser. Someone could end up installing the 8.1 update on top of 8.1.

The 8.1 update is a composite of different required KB updates. The 8.1
update is KB 'smart'. If those KB's are already installed then
attempting to reinstall 8.1 on top will fail. If only some of the KB's
are present and not others, then the missing KB's will install.

Note: If some of the missing KB's fail to install then the Windows
component store is most likely corrupted necessitating a component store
repair prior to allowing the missing KB's to be installed.
