While the article does mention non-"binarizing" (I prefer "non-discretizing" as the more common parlance) in the sense of treating the 4 dimensions as axes not buckets, the article does not mention context sensitivity like church-home, buddies, babysitting, same/opposite sex, older/younger, etc., etc.
Per the article, your traits are on a spectrum. Not binary. You may be more extroverted at church and less at work.
