"Implies" means it doesn't have to be spelt out -- it can linger below the surface.
And whether implied or not, it's a legitimate question to ask. E.g. if the kid was asian would as many have the same suspicion given the same evidence (or lack thereof)?
Look at everyone in these replies pretending to be race blind. If this kid was Asian, you'd just go "eh, Asian prodigies" and not give it any further attention.
I have the same feeling here. Although I think it's true that scrutiny is advised in all cases, I don't think I've seen such a critical comment section before.

This is not necessarily a bad thing, if anything it elevates this boy's achievements even more and puts his talents in the realm of once-in-a-thousand-generations.
Nothing in the parent comment implies a so-called "geographical bias", yet there you are accusing them of being racist.
