Interesting. I assumed that as the internal elements of the lens shifted to produce the zoom, the reflections causing the flare would also shift. I suppose it depends on the lens.

Now, if you're referring to the specular highlight, I would not expect that to move in a simple zoom. A specular highlight is a reflection off of some object outside the lens, a lens flare is caused by reflections inside the lens. These are different things. Specular highlights can cause lens flare, but not necessarily every time.
