I think (make that assume) that for many people Dr Smigle was synonymous with the particular teeth product that he brought to QVC. At the same time, they also had a different, if I recall correctly, similarly named product. So, to me at least, it was Dr Smigle that differentiated the two products. Not that I would care between one or the other. But, I can see how bringing him up makes people aware that this was the product he used to rep (in case it matters.)
