What so many UX designers would like you to remember is that UX is not just UI design.
Referring to User Experience Design, people often make a very common mistake: the univocal association with the User Interface Design. The difference between these two branches of Design is sometimes taken for granted and is not correctly perceived from the most. To take a look to job offers on the web is enough to notice plenty of ads addressed in their title to User experience designers professionals but, in the content himself, actually a User Interface Designer profile is required. The fault lies in the idea that the discipline of User Experience begins and ends in building interfaces and hence (in more extreme cases) in web graphics. Nothing more wrong: User Experience Design literally means Design of the Experience of the Users.
