The SGI cult manufactures its history to suit its own narrative and it's narrative, doctrines, and practice has changed several times. The truth is always spun in the SGI cult. They fail to believe in the Lotus Sutra which teaches the principle of thusness [or suchness]. It is useless to rely on the teachings of such people for benefit, let alone for Supreme and Perfect Enlightenment. The Lotus Sutra document has not changed for 2000 years. The theoretical foundation of the Lotus Sutra has not changed for 1500 years thanks to Tientai the Great; and the practice of the Lotus Sutra has not changed for more than 750 years thanks to Nichiren. But in one fell swoop, the Soka Gakkai changed the very doctrines and practice of the Lotus Sutra. They ruined the perfect recipe for Supreme and Perfect Enlightenment.
