Well, let's face it - he didn't have the instruments that modern scientists have, to make precise measurements. He simply made mistakes, just as he made mistakes with geocentrism and epicycles.
There are two possibilities.
First, that Venus was in its current orbit as is traditionally thought, and two of the premiere observers in the history of astronomy, centuries apart from one another, each inexplicably misreported one observation, coincidentally of the very same body, Venus.
Second, that as Velikovsky proposes, Venus was out of its current orbit, and two of the premiere observers in the history of astronomy each correctly reported it.
