What I meant was that yes, the initial product focus is reduced, but there may be a longer lasting and subtler association of the product with the physical attractiveness, which in the end may be more valuable. In other words; I don't necessarily believe that the audience focusing more directly on the product actually sells it better. Most products are boring (i.e. this is just more shampoo), but sexual stimulation is not. Focusing on the sex rather than the boring product is probably to the benefit of sales.
