That's another very good observation about reading things together. Which takes us back to some degree to the related question of "How did Cosma Raimondi get this wrong?". Is this point Don just made what he failed to appreciate?
I might recombine these two threads given that they may be more closely related than I anticipated, but for the time being I'll keep them separate and just crossreference. Cosma Raimondi is probably an example of the interpretation problem, but the problem is much bigger than him.
