git fetch upstream will only fetch new stuff from the upstream remote
repository and will set the FETCH_HEAD reference.

git remove update will fetch new stuff from all the remote repositories
without touching FETCH_HEAD.

Because I always control remotes origin and upstream separately.

You can use "git remote update" instead.

It has no effect, I don't know why he used it. REF~N is used to specify
the Nth commit before the reference REF (for example HEAD~3 is 3 commits
before HEAD, and is the same as specifying HEAD^^^). So REF~0 is the
same as REF.

Yes, it is no effect, but a tag sticks always to a commit, not branch.

The form "REF~0" definitely represents a commit object, even if REF refers a branch.

I used it in order to make the command more descriptive.
