Of course Musk is still Mars focused. That is the goal of what he and the people working at SpaceX are doing. If you watch the source video[1] for the Wired piece (journalists aren't selected for truth telling), you can see Musk controlling the impulse to call NASA a do-nothing, scaredy pants organization. He explicitly states that people going to Mars will not be "safety first" people (implying NASA people are). Musk would love to use rockets to land the Dragons back on Earth but getting them to pass NASA safety tests is too difficult to be worth it with his current understanding of propulsive landing. He and his team have recently determined that there is not as much overlap in the design of a rocket landing Dragon that would land on Earth and the ones they would use for Mars as they originally thought. As Earth Dragon development does not support much of the Mars efforts, they will just go with parachuted Dragon for NASA approved Earth landing and design Red Dragon with more customization for Mars only landing (and liftoff?).
