That's super confusing... do you have a video of it or a screenshot?
Sorry, no. And I don't want to go through the whole ending again to get a screenshot. It's the morning after the ending on the docks and it's like the game can't tell which version of Astarion I have.
This is is a Dark Urge specific line no matter the LI. I guess it simply means that even if you rejected Bhaal you are still a Bhaalspawn and are for example not free to sire children/get pregnant because they'd become Bhaalspawn, too.
