In this case, that's what it means, but in general it means that they shared one parents by blood and not the other.

And you are correct, his last name might not be Vance, but it seems plausible that it is given the relationship between the various relevent characters. I have a cousin who was never officially adopted into the family (he's in it, just not legally and all that) and yet for most of his childhood and years of his adulthood he used my uncle's last name as his own even though it legally wasn't and then when he got married, he made it official and legal changed his last name to match my uncle who was the only father he really had (I think his biological one died when he was younger) and raised him even after his mother abandoned both of them. I see similarities here and can definitely see the MC using his/her stepfather's last name and it's also possible that he/she was adopted and the half brother thing is only being emphasiszed because the biological father is somehow going to be relevant. . . maybe he killed Todd and their mom.
