The 'Chinese' Theory: For and Against

[rikforto]

The middle horizontal stroke of capital letters A, E, H often crosses the legs and sticks out on the sides; but a copyist would not consider those protrusions significant, and would not feel obliged to reproduce them. 

So, the hypothesis here is that he copied a single character upside down from a model that was 1200 years obsolete and did not to transmit the features by which we would confidently identify it? Is there any set of errant marks that COULDN'T be linked to a Chinese character under such a flexible analysis?
