Haha! I think it is funny to watch. The... kicking... legs part. But anyways, to the answer. It is similar to washing your hands after you go to the bathroom and it is also a way to clean their tracks (if the dirt wasn't locked down by the grass).
To further mark their territory using the scent glands in the paws
Licking is the only way a dog cleans itself.

dogs lick people to get to know someone and dogs lick people when their happy.
Your dog is not going to get sick from licking a cat's butt. Animals are always licking their butts.

If dogs do not lick you then they do not appriciate you. Dogs lick you when you give them a treat or play with them.
