you could argue that the VMS is actually a copy

Somehow I can't see that it is a copy. If a copy then it is highly probable that the diagrams would be different to the originals, placed in a different position, different sizes. The writing would have to avoid the diagrams at different places within the text. New lines would start with a different word. This would be especially so if something like hand 1, with a bigger writing style, was copying work originally done by hand 2. But we do know that first line words and last line words have a statistical anomaly to them. If this was also so in the original then line breaks and collisions with the diagrams would need to be as they were in the original.
