Hellraiser Question

Ok, basically I need to know if I misunderstood something. I originally put this under Bittersweet Ending on the Hellraiser page, and someone deleted it saying I misunderstood the ending of Hellraiser V:

• Arguably Inferno. It's implied that Joseph escaped from his Ironic Hell by killing himself, thus returning to the real world. However, now he's had a Heel Realization that will haunt him for the rest of his life.

Someone deleted it, with a comment saying that that wasn't what happened he was doomed to repeat the same thing again for eternity. Now, its been a while since I saw the movie, but what I remember was something to the effect of him being told that he'd repeat the same events forever, but then finding a way to escape, and ending up in back in his office, holding the configuration. Can anyone tell me if there was any indication that I missed that he really was repeating the events, and if so was it intended to be ambiguous,or am I just an idiot?

From what I remember, after he's ripped apart by Pinhead, he wakes up in the motel room, and everything seems fine, and he just assumes he had a nightmare after having sex with the prostitute. He goes to work, but then events from earlier start repeating themselves, so he shoots himself in the mouth. He then wakes up in the motel room again, leaving most people to assume he's in some kind of "Groundhog Day" Loop.
