Yes they do, but do these two things sound so similar that they deserve common name? I think we need to talk about audiophile dictionary in a more critical way, or else it'll continue to be just poetry. Poetry is nice, but for communication's purpose, it's interpreted with more disciplined language. It would be cool to have some intermediary terms that help us with interpretation and link physical phenomena to casual talk.

I'd like to add something that I've been always pointing out. Headphone audiophile speak came from speakers. Words like 'soundstage' are far more descriptive with speakers than with headphones. No wonder, newcomers are often confused. Not everyone imagines headphone soundfield as a stage, more often as a bubble.
