Do you not have the same issue with all numbers under 70? 62 or (60, 2)? And you still have that problem for numbers in the seventies too, it just looks weirder in decimals. "Did you mean (60, 11) or 71?
Even if there is a possible silver lining, it's still arbitrary and weird.
And in English it would be 71 or 70, 1. I'm just pointing out that this meme about french by english speakers makes no sense since it's the same thing in english.
