Caster is the relation of the upper and lower ball joint/mount point in a forward and backward relationship.
SAI is a inward or outward tilt of the wheel in turns that is a result of caster and camber positions.
Caster and camber both have affects on SAI. Its not used in alignments normally because its mostly geometric math related to caster camber and steering angle. And you don't align vehicles with the wheels turned.
