I think that they put it backwards because they either: a) thought it was cute, b) thought that it would remind parents of how to be a kid again, or c) because it was "similar" to the way that kids learned how to write.
Never thought about it though. As a kid I just wanted everything in the store! Like I tell my Mom now, I NEVER DID get that Barbie dream house! Of course to which she responds, "get your own now."
