I think this is looking at the head tilt. Not eye contact or the position of the head. The example photo on the site illustrates the concept. The woman is clearly making eye contact in all three photos, but her head is tilted up and level in the first two. The impression given in the first is a haughty contempt. The third photo is one who you might want to converse or even have a drink with. It's a total attitude shift.
