They aren't slowing the rate of speed near shore just because they feel like it.

All functions of a wake created by a boat are the result of an energy transfer. This energy transfer is directly related to boat displacement. The amount of energy in a wave depends on its height and wavelength as well as the distance over which it breaks. Given equal wavelengths, a wave with greater amplitude will release more energy when it falls back to sea level than a wave of lesser amplitude. The speed of the waves has little to do with this.
A boat on plane displaces very little water and thus transmits very little energy to the water. The low energy waves dissipate quickly. Assuming the boat on plane maintains 150' off the shoreline (per the law) by the time the wake reaches the shore there is little energy left.
This wave energy discussion is the crux of all the proposed wakeboat rules.
