I'm not sure I'd read too much into the "for servers" part.
Everyone expects Apple to switch to ARM chips sooner or later for their laptops and desktops. Their A CPUs would probably already be fast enough for entry level Macbooks, but they still need some higher wattage versions for big Macbooks and desktops. I'm also not sure how good Apples chips are with regard to virtualisation features.
These are all things that would be useful for servers, but Apple needs them for their high end desktops as well. (And Apple won't announce in a court filing that they are working on ARM CPUs for the Mac)
