The 737 had a tendency to tail tip as can be seen here [this video] and here [LINK] . They were just being diligent and of loading people in a timely and organized manner to avoid that. You can read up on it here [LINK] as well.

One thing these answers miss is that fact that there have actually been a handful of tail tip incidents on the 737-900. Since it's happened, then the answer is obviously: yes, it's possible. See, for instance this video [this video] of a Delta 737 tipping. There was apparently just one at TLV [LINK] . United warned its pilots [LINK] about the situation and put in place some procedures to better load cargo and ensure bags are quickly removed from the rear cargo bin before allowing forward passengers off. To help prevent this, United is rolling out tail stands [LINK] for these aircraft. Delta has used stands too [LINK] . This discussion [LINK] at airliners.net has more from some employees who've us

Passenger evacuation for one. Right now, you can open some doors on the side of the tube and add more doors if needs be. That's a lot more of a challenge here. Also, distributing passengers to a wider area inside the body can lead to greater instances of motion sickness. Passengers will generally prefer having windows, which is also a challenge for this type of aircraft. Main gear should be far enough forward that most of the weight is on it, but far enough aft that the nose isn't unloaded in aft CG conditions. It might be right where it needs to be. You'd have to know the CG location. You also need to account for an empty airplane with minimal fuel or it could tip up onto the tail. Tip up.
