That's thanks to the flash. That flash's "pop" lasts for a fraction of a fraction of a second, so even though the shutter is still open, that part of the image will be completely frozen. :)
Here's an example (I didn't take this):
There's a thing called "open curtain" and "closed curtain" flash. The "curtain" that it's talking about is the shutter. Let's say you have a shutter speed of 1 second. "Open curtain" flash is a pop of light at the beginning of that 1 second. "Closed curtain" is at the end. I'd bet that the card in the example above was closed curtain because it appears the that the last thing that happened before the shutter closed was that pop of light to freeze the card at the end of its own trail. Had it been open curtain, the card would be at the other end of that streak.
lol That IS the blur. Or are you talking about blur on the person?
hahah I was talking about blur on the guy and everything except the fire :P
I thought his hand would be blurred slightly.
