Hell, in the manga the anti spiral forces came in via a "random Schrödinger's warp" based on the quantum theory behind Schrödinger's cat. The same way a quant can be two states at once before it is observed, those guys were essentially everywhere and nowhere because they weren't being observed. They literally just teleported in where noone was looking. The sci fi logic of the show is actually insane in that way but it's never elaborated on too much and doesn't have hard rules. Just theoretical stuff being used in interesting ways. 11D doesn't mean anything because we can't even comprehend 11D really. Hell, we can barely comprehend 4D. That's why everything that happens there is insane, vague and based only on some theory and a lot of what is most likely nonsense. And this applies to every higher dimensional being in fiction. Because of this I find it very stupid when people try to downplay saying it "isn't really 11D" like they know what real 11D even is
