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.

I've posted a picture that compares option 1 (scaling to simulate spread) with option 2 (offsetting to get spread):

Option 1 is not as terrible as I thought, but is still furthest from normal expectations, with uneven amounts of spread around the corners.
