That's because the description was written by a person that started out with the view that ENFp is primarily defined by dominance of Ne's "interest in ideas". Its circularity at its worst.until you read the alpha extrovert descriptions, then you can easely distinguish between them. But if you really think that 1 might be ESFJ then I find that extremely strange. The first line just screams Ne. It's almost litteraly what Ne encompasses.
