That is assuming he's right and that moving at the speed of light really DOES slow down the time for that wave.
On equations, time does slow down. And since nothing is faster than light, they simply put that the distortions in time-space caused by mass is as fast as light.

It is theoretical. It doesn't have to be as fast as light, an object simply has to be very, very fast.
