Default Q7 - understanding co-ordinate descent

I didn't entirely understand what co-ordinate descent meant. This is what I believe it to be: Instead of descending "simultaneously" along all the co-ordinates as in gradient descent(in this eg: both u and v), we first descend along u, find the new u and then find v. So, when computing v, the new value of u is to be used. Am I right?
