Maybe the question should be "why did some riders/mechanics stray from the well-established (and blessed by Tullio) practice of putting the lever on the right side?"

Campy hubs were delivered with the lever on the right inside the box well into the '70s. Though you had to remove the skewer to install the freewheel anyway, so it didn't make any more work for you to flip it on re-assembly.

Notable in this one, the hub in the lower-right is a Pista! (Note curved levers)

Did they picture them "wrong" in all those catalogs, even into the '80s, as some sort of in-joke, or was this really how God and Campy intended them to be run?
