They based it on his skin colour, accent and the way he speaks. I’m not fluent in Spanish and Mexican dialects, but in my country I can tell what part of the country people are from as well as education level based on how they speak and what vocabulary they use. So if you add his skin colour (lighter than the indigenous people in Chiapas region) one could make an educated guess.
As I said I’m not familiar with Mexican accents so I can’t confirm, just relaying something I read/heard. His speeches are on youtube, so perhaps a comrade from Mexico could confirm/deny.
I mean, unless he’s mestizo, which would prove settler-Spanish roots, are we really sure?
