I'd prefer to think of it as a "popular trope" thrown in to increase reader engagement
"Popular trope" in quotes because I don't understand why it's popular. I understand the step-sibling romance trope is popular because it's a easy way to get the love interests living together before they're dating.
That's generally it. Incest is a popular trope regardless of sexuality and country, porn in the USA typically doesn't venture into blood related incest stories, I think because there's more red tape, but step-family incest is one of the most popular genres of porn by a huge margin. With Japan there's a recent hetero anime about step-siblings, Citrus is one of the best selling manga with lesbian romance. Blood related stories do sometimes happen. I will say it's definitely not just a gay or Japan thing, incest blood / step-family related is just hugely popular in fiction in general.
Also as for if they expect the audience to empathize with it, I don't know? I don't self insert into media and I take it generally for what it is. Maybe some people empathize with it, I bet most just consume it as a spicy taboo story. People also consume tons of extremely violent media, and that's almost never questioned. Slasher movies were at one point in America one of the most popular and successful film genres. Violence is pretty popular in general with media and humans like things they probably shouldn't, it's often a core trait of humanity lol
Edit: As long as people can separate reality and fiction, that's the most important thing I think.
