You have a "question" and "it relates to a contributed package", so
the premises of the second (and not the first) sentence is satisfied.
The consequent is "contact the maintainer". Logic ... simple clear
logic applied to a declarative English sentence.

Your interpretation is perverse and I assert is completely contrary to
doubly perverse in that it regards the package documentation which
_only_ the maintainer can adjust. I do not undertand why you are
with these persistently obtuse questions while you are at the same
time resisting contacting the one person who could do something, the
package maintainer.
