Consider the difference between the inside and outside radii of a border whose 'border-radius' measurement is close to its 'border-width'. It is a big difference, with the inside at or near zero radius. Now consider how little you have to scale a typical element to get offsets of a few (or even several) pixels. Hardly any at all, so that the corners look very odd, not much at all like a real offset.

Okay, I have to admit that the scaled spread isn't quite as pretty.
In that case I support whichever option Brad is advocating.
