I don't think it is anything new per se, but there is definitely some confusion when doing a HILO approach when you are approaching the IAF from a direction when you wouldn't normally hold. When you are told "maintain X, cleared the approach", it means that you are going to fly the entire bold line, including a procedure turn or hold.
I usually just ask for clarification or request "direct Y for the straight in RNAV". This will just clarify any confusion.
