So, this exemplifies their _good_ work?????

It would be nice if they included something about being
_at rest_ before and after.

This criticism is /partly/ nitpicky, because a teacher with
ordinary skill in the art could figure out what was intended.

OTOH when an _authority_ puts out supposedly _definitive_
definitions with this degree of sloppiness, it indicates a
lack of care.  This is their "good" work??!!??

I'm not shocked by mistakes, but if mistakes are allowed to
persist it indicates a badly broken quality-control process.
