Some special process in lanczos3 resizer?

I have a question about Gimp's lanczos3 image resizer.

I found that the results enlarged by Gimp lanczos3 resizer look very different from other implementations' such as ImageMagick. I tried implementing simple (no optimizations) lanczos3 resizer, it generates the same results as ImageMagick.

Gimp's one looks much better for me because of its less jaggies.

Does Gimp's resizer do something special?
