If read carefully (some may argue that it does not need a very careful
reading to get it, though), this hints that "detached HEAD" state is a
substitute for using a temporary branch, but it may not be strong
enough.

For my rather fresh eye it looks more like unnamed (anonymous?) branch
than a temporary one. Doesn't detached HEAD behave exactly like a
regular HEAD but pointing to the tip of an unnamed branch?
