The key question is: is it clear, reading Jung's Introverted Sensing and Extraverted Intuition description, that they complement each other? And not just "they complement each other because they're supposed to".
In socionics, the very nature of

and

means that they complement each other. It is as much part of the nature of an IEE to seek

above all in other people, as it is to provide

. It's not something that "just happens" - it is an integral part of it.
Personally I think that to assume that Jung is the One True Source of socionics is a sign of intellectual laziness - much easier to assume that all you have to do is to read Jung rather than try to understand how socionics differs from it, in its own terms.
Can we really say that Jung's Introverted Sensing and Extraverted Intuition types really, necessarily, complement each other? I doubt it.
