I am a native speaker of English, so I intuitively pick up the meaning in bold from a sentence spoken as follows:
The contrast between the perfect and non-perfect takes on more significane when Tsit is of relatively long duration, especially with "as soon as" and (to a lesser extent) "before". Thus while the perfect is omissible in "She left the country as soon as she had completed her thesis (punctual Tsit), it is not omissible in "She left the country as soon as she had written her thesis" (where the thesis-writing situation is too long to be compared with the country-leaving one). Similarly "She left the country before she had written her thesis" allows (and indeed suggests) that she had started writing when she left and is thus not equivalent to "She left the country before she wrote her thesis.", which indicateds that the leaving preceded teh whole of the thesis writing.
BrodieSWR The combination of the before and the past perfect seems like a paradox. When you consider only the usual uses of the past perfect, it is a paradox. But this combination is a special use which indicates the interruption of one action by another, or, stated differently, the non-completion of one action because of another, interfering action.
