When you dig a hole in clay the bottom and sides are clay which fills up like a bathtub. When you build a raised bed the bottom is clay, but the bed is above ground level. When the excess water reaches the clay it can leach out of the raised bed through the bottom where it meets the soil and through any seem or hole in the wall of the bed. Also since it is above ground level you won't have water draining from other areas into the bed. It will only receive water that fall directly on the bed from rain or hose.
