Well, it's an ad, so what it actually points to is an advertisement agency deliberately going out of their way to cast interracial couples for reasons that have nothing to do with the personalities of the actual people involved.

But as to your point, probably a different chart, but yeah, I saw some statistics from a dating site that tracked every race's interest in dating every other race, and every race had a significant in-group preference, and a significant preference against black women. Except blacks, where they cancelled out. Basically, the races don't agree on who's most desirable, but they do agree that black women are the least desirable.
