                In TurboCAD set back refers to the distance back from a corner that the constant radius ends, where the blend into the cap where two or more blends meet begins.   In the pic I've got a standard 10mm three-face blend without setback, and a 10mm three-face blend with two setback figures, 10mm and 20mm.  With no setback, the cap is a spherical section, with setback it's a lofted shape.
In chamfer, it's meant to be the distance back from each edge that the bevel is taken from, if they're the same it ought to be 45 degrees, if they're different the angle will be too.  It's similar to a hold line blend, I guess.  In chamfer it works with two lengths option.
Realising that, it's probably the same condition with elliptical blends.
