Can a Plan compute the soc. sec. benefit (used for purposes of the offset) on the basis or method that assumes that the person terminates due to disability?

That is, the soc. sec. benefit would be computed differently. As I was told, in the determination of AIME, the denominator would no longer be the typical 35 years, but would be based on years up to time of disability. i.e. a much lower number in the denominator.
