That still doesn't imply "naturalness". Quite the opposite. It implies that both are natural since both are adopted and both have been switched to after previously adopting the other.
Remember, too, that most people consider every system that they learn first as "natural". Like it's equally true that historically people did not select base 10 very often. Base 12 and base 60 were both popular as well if they're even using positional numbering at all. Nevermind how long we went in positional numbering without a zero. Is zero then unnatural? I think it must be. Is "naturalness" even virtuous then?
"naturalness" is a rather pointless thing to argue over. I only mentioned it in response to the parent (and I only mentioned it in the article to highlight how arbitrary it is).
My point in the article was that the numbering system was originally little endian because it made things easier when multidigit numbers grow in magnitude in the same direction as you write (least significant digit to the right in this case as it was a right-to-left writing system at the time). This written ordering was then maintained for compatibility reasons in the parts of the world that eventually settled on left-to-right. And the vocalizations ultimately followed those of the dominant cultures of the times - which used left-to-right (with some vestigial exceptions - see my sister comment).
