Note that for d odd the 2 n/d-gram layers are aligned in a gyrated way, which then effects that top and bottom vertices are situated on gap. While for d even the 2 n/d-gram layers are still aligned in a gyrated way, but this time it effects in a seeming ungyrated parallel alignment, just like in the mere n/d-p, but now with crossed lacings, so that the according height becomes lesser than 1 here.
