This is related only to "maximum r.p.m. for level flight", described in paragraph (a) of the (vi), not related to "maximum boost for level flight" described in paragraph (b).
Of course the violation in these condition is not intended. It's caused by the constant speed propeller that has a certain delay before it can counteracts a increase/decrease of engine speed.
