Another problem with people conflating "UX Designer" with "UI Designer" is that if you put "UX" in a job title hoping to get "UI" folks, you will get the wrong people. I have seen this first-hand now with two companies: the job title was set by someone who didn't really understand the difference and instead of getting qualified visual/interface designers applying for the role we got people who draw boxes and arrows, extremely low-fidelity wireframes, and user researchers. Not people who cranked hard on the actual product, but people who did a lot of "meta" work that only affected the product in passing.
In larger companies there may be a need for "UX" designers like that, but at small companies when people all need to wear multiple hats, you don't just want a wireframer or flow diagrammer... you want a designer who can think about the overall experience, then design it, then create the actual pixels, then hopefully write some front-end code as well. I have yet to meet anyone who considers themselves a "UX Designer" to be able to do any of that.
