Copying phrases is universal among the verbally adept, and the shapes of things evolve with obsolete features copied forward. The motor car is a fine example of that. Artists copy so well that the steam engines in childrens' books are still drawn with the boiler and cylinders properly proportioned, while dozens of engineers get it wrong in their inventions. The Parthenon "looks right" spectacularly well, but among the frescoes are things needed to look right to the builders - fake peg-heads, as if the stone beams were still made of wood.
However, Aspies have rather poor function in the mirror neurons. We notice them working, while NTs may never know them to be off. Back when teenagers talked, you could often hear almost nothing but trendy quotations and stock insults being bandied back and forth. So, on average, we do more original work. I have been astounded at details my apprentices have noticed and copied, while I learn very little from watching others. I'm always slower at routine tasks, and usually faster at original work.
