@jacquidow, this is a great question. I would still call it a UI position. When you are a UXer you have more responsibilities about the process and generating the knowledge about users interacting with your business, conducting user interviews and usability test sessions and all other kind of research tasks. That participation in data collection from the day first, engaging with users, flows, empathy maps and all other related deliverables can make it more toward UX, and I don’t see this happening much in what you described.
Asking “why” is still part of the UI Designers jobs as well as the UXers, and UI designers still need to know about UX journey and stuff like that, but what makes a difference is the one designer who researches and spends most of his/her time creating those (or has attempts to making those happen) with the other designer who is reviewing those and extracts more detail insights from that in order to create a unique user interface following the brand values and guidelines.
