Then we should also consider those 12 cases where this glyph has been split up into a pair, all of them on side b of the tablet:

Ab1-19--20	Ab1-26--27	Ab1-35--36	Ab1-40--41	Ab1-62--63	Ab1-77--78
curved henua, leaning ragi with right flame small	hatched interior of henua	narrow henua leaning towards left	narrow henua leaning towards left	tall straight henua	short straight henua
Ab2-1--2	Ab2-18--19	Ab7-10--11	Ab7-77--78	Ab8-22--23	Ab8-35--36
great straight henua, front vertical line longer in ragi, long flames	short straight henua, front vertical line longer in ragi, long flames	curved henua, back vertical line longer in ragi, big flames, big head drawn down at left	wide gap between curved henua and great ragi without vertical midline, great flames, big head drawn down in front	curved henua, central vertical line longer in ragi, big flames, big head bent towards left	both glyphs great, head of ragi drawn down in front

Could this separation be a way to illustrate how there once upon a time had been a separation between Heaven (Ragi) and Mother Earth?
