This is Berkson's Paradox. Even if coding competition performance correlates positively with job performance in the general population (which it certainly does, given that most people can't code), selecting for this attribute in the hiring process leads to a negative correlation among those hired.

Depending on how they define "winner at programming contests", this might narrow down the population to just a handful of "sport programmers". The same handful of guys win all the contests.

The statement might as well be "tourist has bad job performance". (https://en.wikipedia.org/wiki/Gennady_Korotkevich) And that isn't surprising given how much he has to train everyday to stay on top. He even turned down offers from Google/Facebook just to continue qualifying for the big annual competitions like Google Code Jam and Facebook Hacker Cup.
