Still confused with Bernard & Arnold

When Dolores is being shown around “real life” at the beginning of EP2, it’s actually Arnold showing Dolores around his “house” that has not been built yet. But, it appears to actually be Bernard. Can anybody clear up this confusion for me? I know Bernard was built was Ford to honor Ford & Arnold’s work together, as If he were a somewhat of a “clone” of Arnold, so they could still continue their work. Why is he appearing as Bernard if Arnold has already passed away?
