Bingo! I have seen many people get confused on this and basically end up with their elbows up (45 degree or higher) and more or less pushing on the bar thinking this is what is meant by bending it around their shoulders.
Elbows down (ideally parallel with your trunk)and pull on the bar to bend it around your shoulders. This will help alot in keeping your upper back tight, chest out and helping you stay upright through the transition.
Oftentimes, a beginner lifter will not have enough meat on their upper back to do this effecively without a high bar position (because the bar will slip) and will need to thicken up a little before this becomes easier.
Also, longer limbed/larger lifters may have to have their elbows somewhat behind them because there is just not enough room under the bar. However, you should always focus on pulling on the bar, not pushing.
