What is the difference between Spread and Blur radius properties?

I have read that spread value makes the shadow bigger. Isn't this achieved by increasing the Blur radius or increasing the x and y values?

From this article

"The blur radius (optional) - if set to 0 the shadow will be sharp, the higher the number, the more blurred it will be.

The spread radius (optional) - positive values increase the size of the shadow, negative values decrease the size. Default is 0 (the shadow is same size as blur)."

I made this pen which might help to see the difference.

Hope this helps :)
