This happens because in the frag function in Internal-DeferredReflections.shader eyeVec is calculated as normalize(worldPos-_WorldSpaceCameraPos).
This calculation is correct for a perspective camera but not for an orthographic camera. You'd need to replace _WorldSpaceCameraPos with the ray's origin point on the camera.
