I think the more likely meaning of that passage in the Samdhinirmocana Sutra is that it is referring to the teaching that a fully Enlightened Buddha doesn't pass into Parinirvana and then not help living beings anymore, but that they merely manifest a showing of passing away into Parinirvana to instill a sense of urgency. This is mentioned in Chapter 16 of the Lotus Sutra where the Buddha says:
"Thus, since I attained Buddhahood, an extremely long period of time has passed. My life span is an immeasurable number of asamkhya kalpas, and during that time I have constantly abided here without ever entering extinction. Good men, originally I practiced the bodhisattva way, and the life span that I acquired then has yet to come to an end but will last twice the number of years that have already passed. Now, however, although in fact I do not actually enter extinction, I announce that I am going to adopt the course of extinction. This is an expedient means which the Thus Come One uses to teach and convert living beings.
"Why do I do this? Because if the Buddha remains in the world for a long time, those persons with shallow virtue will fail to plant good roots but, living in poverty and lowliness, will become attached to the five desires and be caught in the net of deluded thoughts and imaginings. If they see that the Thus Come One is constantly in the world and never enters extinction, they will grow arrogant and selfish, or become discouraged and neglectful. They will fail to realize how difficult it is to encounter the Buddha and will not approach him with a respectful and reverent mind.
But a Buddha can still send out other emanation bodies to help living beings, and also help by teaching high level bodhisattvas with their Sambhogakaya in their pure land.
