That can happen. Depends on the strength of the respective 3G and EDGE signals.
I've had times where I had a 5 bar 3G signal, and 2 bar EDGE signal, and vice-versa. In a low-reception area, EDGE is much more efficient at saving battery. But in a deep metro area, there might not be much difference, but if 3G is congested, EDGE can sometimes be more efficient for this situation.
