I am not quite sure I see where you are going with this personal perspective in regards to the geometrical concept. Is it an error or one that seems to be a state of confusion in reality as well as theory and perception?
But I do feel honest personal testimony is important for the critical evaluation of a work until its level is surpassed by greater wisdom, the comforting truth for awhile anyway.
If a chiral object like a muon creates its own "everything else" null space (see Rowlands) then we can imagine two types of such space as well as that distinction you make with such particles. So yes it evokes ideas of dark matter and related to further thoughts on the role of time and tachyon theory (as hinted in my simple post today on quasi-stable lattices.)
But the chriality is not everything or the most foundational thing for say galaxy creation from quasar like objects.
We may imagine the 3+1 and 2+2 formulations equally well so in a sense that is not a mistake while it can be a natural confusion. It certainly is not a mechanical blunder.
As there may be a picture of a previous state of the universe as to the precursor black hole like objects- a pre-hydrogen or neutronium era, certainly the physics of this state needs to be developed uniquely so there is still a vast world of work to do.
