I see what you're saying but the two waves are always in phase as shown. The reason they don't go to zero and stay there is because they are changing together. A changing E field makes a B field that is changing (not static) Therefore they change the most at the same time. If one peak was at a maximum (or minimum) while the other crossed zero (biggest point of change) then the changing field would be making a non-changing field, and that would make the wave not work. I had the same thought once and my E&M professor set me straight. He probably said it better than I did though...
