Yeah, I don't think that helps your point. Sure, a character can affect space-time on a universal scale, but does the space-time continuum itself remain intact? If it does, this doesn't qualify for AP and is more likely just high-level Space-Time Manipulation. Another contention would be the word "absolute" we can't really infer from that word how much dimensional energy is released. It could just be a description of how effective or precise the power is in-universe. Lastly, you said it yourself: "within the universe". I think that in itself is a disqualifier, as you would need to destroy or create the 4-D structure as a whole, rather than just messing with things inside of it.
