That quoted paragraph is a pretty clear indication that the "instinctual reaction" only happens with people you've lived with up to the age 6, which isn't exclusive to people you're related by blood. Hell, the following wiki paragraph makes that clear:

In Shim-pua marriages, a girl would be adopted into a family as the future wife of a son, often an infant at that time. These marriages often failed, as would be expected according to the Westermarck hypothesis.

So, if you don't grow up with your siblings during those formative years, or see them only on occasion, it is expected to be attracted to them, as per that hypothesis. It's also important to note that marriages aren't a simple matter of choosing whoever you like most, there are social and economic considerations to be accounted for.

You're talking past each other: Chicken is saying that we have a biologically ingrained aversion to mating with those we lived closely with up to the age of 6, and is suggesting that this is a result of evolutionary pressure making it preferable to avoid having kids with your nearest relatives.

Their point is that this is not "taught" behaviour in the sense that it is imprinted from culture (such as "what hairstyle is attractive" or "what music is pleasant"), but appears to be biologically grounded.
