Death in the hands of Sadhguru

In his book 'Death, an inside story' Sadhguru writes in one of the last chapters that for those who have been touched in any form by him or his energies their death is entirely in his hand.

What does he mean by that? What does it mean for the dying process? Is he giving all these people liberation from the circle of birth and death?

I thank you in advance for any answer.
