That's not really correct. A torus is a 2-dimensional manifold that can be embedded into 3-dimensional Riemannian space. The author of the article is correct talking about a three dimensional torus as it's defined as S^1 x S^1 x S^1. You can also check the wikipedia page (https://en.wikipedia.org/wiki/Torus) that defines an n-dimensional torus in the same way.
Thank you for explaining this, something was obviously missing. Living on a 7 meter torus would be challenging for many reasons, but seeing many cylinders or images of yourself wouldn't be some of them.
The author is talking about toroidal space which is confusing because a normal torus is a three dimensional thing with normal Euclidean geometry.
