That's sort of what I was thinking, that one would be
AB
CD

while the other might be
BA
DC

or any of the other arrangements.

I don't know how the two different stitchings were arranged.
To me it makes sense to have both of each type together, as an indicator of what part of the sheet was being looked at if there was a problem.
Sort of like how a bunch of injection molded stuff has numbers molded in to identify which cavity of a multi cavity mold a part came from.

Yes, possibly like the * vs ** indicators after production and packaging moved to Duryea in 1966. The asterisks were introduced at that time by Ben Solomon (who was at Topps when the 52's were printed BTW) so he knew which slit he was looking at in the proofing process.

I added the referenced proof sheet and edited my post after you responded Steve.
