Well, maybe but the condensate drain doesn't always go into the sanitary sewer. One reason I've seen it done on some systems is that if the cooling coil is on the suction side of the blower warm air will be pulled into the coil through the drain line.
A trap on the line prevents this. The goose neck has to be tall enough that the suction can not break the water seal.

1. To allow the water to cool off before it goes down to the grass or flowers underneath.
2. To prevent obnoxious gas if it's draining into a sewer line.
3. In both cases, to prevent or discourage small animals from getting into the AC box.

If the drain is connected to the sewer, it is required to keep the sewer gasses out. If it justs drains to the outside, you don't have to have it, but it keeps insects from getting into the house.
