Abomination Buffet EQ All Buffs?

Is Buffet supposed to clear all buffs off the attacker at the start of the fight? My VTD lost all 10 buffs at the start of the fight but the description clearly states "buff" not "buffs".

Just a single stagger is enough to nullify all buffs that activated at the same time.
Meaning if a stagger was on VTD and he did sp3 to gain his 10 buffs in the RNA bank, that stagger will nullify all 10.
Not sure how other champions' staggers work the same or not. Such as Juggernaut and Thor Jane Foster
