That should be clarified to be only relevant to explicit rules.

Pattern rules can never have multiple target definitions, even if some
are order-only definitions, because any pattern rule statement that
doesn't contain any recipe _deletes_ that pattern rule.  See the GNU
make manual for details on this behavior.
