Your point is well taken, but actually it has been a trend that has gone both ways. I have baits with basic craw painting dating to the 70's (cannot remember the names and not on the lure), and some of them had the claws on the correct end. Others, well I suspect most lure paint schemes were done by artist in some factory in China and not by biologist of experienced fishermen.
But, as you and Bob have pointed out, if it is a reaction bite, like most crank baits, it probably does not matter all that much.
