Note that there is a broad paint stroke (E) that runs straight over one of the stitching holes (F), across the whole pond.  Moreover, if the thread was still there, the  greenpaint would have collected under it and left a "shadow" of the stitching.

  
  This hole killed my theory

  I had read that somewhere the internet, and I tried to find a source.  Surprisingly, is seems that it is still disputed whether such thing was ever done.
  
  It seems that some Medieval Jewish scholars described that practice and even gave distinct names to unsplit vellum and to the two layers of split vellum.  
  
  However, the author who wrote the entry on vellum for the Diderot Ecyclopedia in the 1700s claimed that split vellum was just a Medieval Tiktok meme, and when he asked contemporary vellum makers they laughed at the idea.
  
  So, what is the truth?  Presumably only the thickest (calf?) skins can be split, and the process surely would require special tools and skills.  Are there extant manuscripts which were definitely written on split skin?

  Sheep parchment: Generally thicker with a greasy texture, often showing hair follicle patterns.

  Production of parchment in the Middle Ages according to descriptions in various books. 1100-1500.
     
  It is not split, it just looks that way.

  Yeah, I have seen several videos of parchment making at companies that supply restorators and such and use traditional methods.  They just don't say that split parchment is not a thing; they just don't mention it.  
  
  BUT it would seem that sheep and deer skins are too thin for splitting anyway.
  
  BUT there are those Medieval Jewish sources that seem to speak about split vellum as a commonplace thing and give names for unsplit vellum and for each of the two layers of split vellum.  
  
  So I am still in doubt...

  I have never heard of split parchment, nor have I ever seen it.
  I would imagine that this is a translation error.
  In the case of scrolls, I could imagine that the adhesive joints of the individual sheets were cut at the adhesive joint and inserted into each other to achieve greater stability.
  Otherwise, I can't think of anything else.
