Yes, but if the Dyson sphere is 2 light hours away from the planet, the planet will cross the actual geometric line between the Sun and a given point on the Dyson sphere two hours before the shadow is visible.
What you're saying is like saying that vision is faster than light, because I can look at Sirius, and then look at Aldebaran a second later.
