An introvert is "a typically reserved or quiet person who tends to be introspective and enjoys spending time alone" [1]. So I agree with you that it is surprising to be a "complete introvert" and to look for social interactions with strangers, even though they are 1-to-1. The people whom I met and who are extremely shy or timid would tend to avoid these, I think.
That being said, I can see how the poster would define himself as an introvert (avoiding social gatherings with a crowd), and be more comfortable alone or with 1-to-1 discussions (actually 3 people, since there is her friend as well). The adjective "complete" in "complete introvert" might be exaggeration though. :)
