CSS vs CoffeeScript

In the video

http://teamtreehouse.com/library/programming/build-a-simple-ruby-on-rails-application/frontend-development/adding-interactivity

Jim Hoskins adds some CoffeeScript to include a class on the action of hover. My question is: why not just use the suddo class of hover. In other words, in the css file I would have written: 

.status:hover .admin {
    display: inline;
}

.status:hover {
    background: #FAFAFA;
}

The end result is the same. Is there an advantage or disadvantage to using the CoffeeScript?

Many thanks, Drew Butcher

I originally thought it was so that when someone hovers over all the whitespace to the right in the status fields, the jQuery would cause the hover effect where CSS wouldn't. However I tested it, and you're right Drew, CSS works pretty much the exact same way. Maybe it was just to intro a bit of coffescript, I s'pose.
