ISTM that the point is not that it is wrong, but it could be more precise.

It does not say "reuse" explicitely, it says
"prepared: use extended query protocol with prepared statements."
but the extended protocol does always "prepare" statements before
executing them, the difference are that with "-M prepared" (1) it is done
just once and (2) named so that it can be indeed reused.
Note that "extended" prepares much more statements than "prepared":-)

Sure. At the protocol level "prepare" is slightly imprecise, and the
documentation is about the protocol used.
So I do not think a more precise wording harms. Maybe: "prepared: use
extended query protocol with REUSED named prepared statements" would be
even less slightly ambiguous.
