I understand the concern, but if we, per your argument, accept that portion as unreal, then the obvious choice is a dream sequence. Then, all it does is reinvigorate Yang's search, when she hadn't made any recent progress. This also explains why she looks almost too similar, by some people's lights: Yang's basing her mental image on the photos she's seens, which are seventeen years old, at this point. No wonder she looks so young!
