If they are bent by the same amount, they still would not overtake each other.

If I'm not mistaken, the starship never fire a photon-torpedo unless the shield is on. And the starship cannot travel at warped speed when the shield is active. But when escaping, one's intention is not to fire ahead but to fire back.

Thomas Young's double slits experiment was used to prove the wave properties of light. In this context, it can be used to prove that light from different sources will always interfere and so implying that the wavefronts of photons from from the same source will never overtake each other. See the following interactive website, demonstrating the effects of the experiment.

When considering the wavefronts from a single source, the leading fronts are assumed to be closed spherical surfaces. Each separated by a distance. This distance can be defined as ½ a wavelength if the concentric spheres alternately described positive and negative modes of spacetime influence. However, the existence of this distance implies the existence of two irreducible point sources as the seats of electric and magnetic fields. Radiative transfer is then due to the fact that electric metric is greater than the magnetic metric and the reverse is true for standing matter waves. When these metrics are equal then we have spacetime quantization and the speed of light is set equal to 1.
