Forum:All Out Attack with Book of Moon/Eclipse?

i attack my opponent's spear cretin on the field and he chooses a flip effect monster while All-Out Attacks is active. his monster is forced to flip up and the effect activates. he activates Book of Moon to flip it face down. does it flip back face up again due to AOA? i am already aware that monsters who are special summoned and flipped down by an effect is still considered special summoned monster and monsters force to flip are not flipped summoned. so in short, does All-Out Attacks force my opponent's monster to flip up again if it was flipped face down due to an effect?
