There's nothing artificial in those cells. Everything is natural. The genetic material was "chemically printed, synthesized and assembled [sic]" and then inserted into the cells. Here "artificial" is being used as man-made. WHich is quite alright, mind you. But to me, just an extension to the concept of cloning.
I happen to look at artificial life as a life-form that doesn't depend on chemical reactions to live, reproduce and sustain itself. That is, "Artificial" as being outside the scope of nature.
