All of this because as Kaworu said in 3.333, Eva Unit 01 was the trigger that started the Third Impact (only to be temporary stopped by the Cassius Spear).
My guess is that when the 12th angel took control over Mark.06 (by SEELE's programming) they had the need to remove the Cassius Spear from Unit 01, so it reactivated again as the trigger for said Impact with the bottomost part of Central Dogma as the new epicenter.
That does raise the question that if A3I was "hijacked" back by EVA-01 when the Cassius impaling it was removed, changing Lilith's head to Rei's and the FoIs at its image, then how was it stopped afterwards without spears?
