I agree it's unfortunate. I think this is really a flimsy use of a technical term which does have a precise meaning in the context of mathematical physics to make the idea of multi-dimensional array seem "deeper" than it really is. There are enough hard problems in data science - I don't think it needs to burdened with terms like this.
