Kosher salt actually has nothing to do with keeping Kosher within the Jewish faith (although, kosher salt IS Kosher...)
In this case, it refers to another meaning of the term "kosher" which means to preserve by salting. In this process you liberally salt the meat to help pull out moisture that bacteria could live in and spoil the meat. The larger flakes of kosher salt make it easier to stick to the meat in a nice even layer.
To make something Kosher it has to met the guidelines of kosher outlined by Jewish law. Kosher salt is certified as kosher by a rabbi or by kosher certification agency insuring that it contains no additives. It is used by the Jewish faith to draw blood out of meat so that it meets the dietary rules set by Jewish law. The grains are larger than table salt so is not adsorbed as much and can draw out the blood and then washed off the meat.
It's a misnomer. Kosher salt is coarse salt used in the process of koshering meat. It should be called KOSHERING SALT. Of course the product itself is kosher, but not more specially kosher than any other product with a kosher certificiation given by a rabbi.
I think it differs because kosher salt is additive free plus the grains are bigger.
