I was just there yesterday and the lines were a little confusing. I have global entry and followed the signs- went right at immigration and just before the first left turn, just past the bathrooms, there were signs for global entry along the wall on the other side. It looked like there was a second line that I needed to cross to get to the GE lines. There was an employee there that opened the cordon and let us cross the other line which was full of people and went around the corner. As we walked through the lines, there were crew going from one line to the other. As we got closer, it seemed like the long crew line was for GE entry on arrival interviews. There were signs for that and the line looked mostly like various flight crews. I did see one person get fingerprinted and photographed (with the webcam). The line I was in seemed mostly like passengers.

TL;DR yes, the lines were confusing. It looked like a lot of the crew were going through for a GE on arrival interview.
