I believe will always default to sending the PR to the remote named origin. If you have the original repo listed as origin and your repo as a remote with your username, you get the expected behaviour. I think the issue here is that hub has no explicit knowledge of the ancestry of the repo so unless it fetches this from the GH API, I think it's doing the only logical thing.
