This is true. In my ethics class we are taught to never ever say that word. Not only because it may 'confuse' the patient, but it could also confuse the therapist, if counter-transference ever occurs, furthermore it changes the dynamic of the relationship. And then the patient has to deal with the pressure and what you mean by it etc. It's best to avoid the word at all costs. It's a very inviting word and not in a good way. It can lead to a lot of hurt feelings, misunderstandings and miscommunications and can actually disrupt the therapy.
