Absolute Will = user can manipulate all of totality as they see fit.
Alpha Reality = user can manipulate the "true" reality underlying all realities.
They achieve the same thing, more or less.

Absolute Will is a sub-power of Omnipotence.
Alpha Reality is an expression of Omnipotence.
Omnipotence transcends logic.
Logic defines the mechanism of a power.
No logic = no mechanism = no difference.
Omnipotent powers are indistinguishable; any "mechanism" is vestigial.
