Leaves blow around in the wind. If water was not being repelled from the underneath of the leaf, it would gain added weight, and have the potential of anchoring the leaf in the wrong direction. Repelling water from the underneath of the leaf keeps the leaf light, which allows the rest of the plant structure to support the leaf in the proper orientation.
