This is a compounded theory by hear me out!
Theory number one: The original pacifista were modeled after the ancient robot that's in Egghead, including some of its programming.
Kuma, the original pacifista suddenly attacks Mary Geoise recreating the very same incident from 200 years ago done by the Ancient Robot.
Saint Saturn, will take back the authority of the pacifista meaning, unless he's taken out, the pacifista can't be stopped.
Theory number two: Joyboy or in this case Luffy has the highest authority.
Luffy commanded S-Snake to stop using her powers against his friends and to turn them back, Jinbe/Stella thought this was due to the original Boa Hancock's feeling towards Luffy. Which might still be the case BUT that in its self makes no sense as Hancock did not fall in love with Luffy so easily.
I believe Luffy unintentionally gave his order to S-Snake, in which overwrote York's order. No one other than the Gorosei have that authority, but if the Ancient Robot is reacting to Luffy who was seemingly powered up by the drums of liberation, them Luffy learning this can control the Mark III's, Seraphims as well.
