Doubts about the electron magnetic moment.

Hi.
According to this page and other sources I found the zcomponent of the electronic magnetic moment is greater than the classically calculated value due to relativistic effects. Which makes me wonder: 1) What about the x and y components? I am completely lost as to why only the z axis is mentioned. I'm thinking that it is assumed that the axis of rotation of the electronand therefore the moment are aligned in that direction and therefore the x and y comps are 0. Am I right? 2) How are relativistic effects sneaking in here? There isn't anything going really fast, which I thought (perhaps naively) was necessary for them to be relevant. Thank you.

Does that different description of electrons happen to be the Dirac equation?
