Yeah, this mostly applies to less than senior candidates. That said, the argument is that the code is quite a bit secondary once you dig into their work-history, references and so on. If they can code, and the other data backs things up, then its easy to see whether they would succeed in the role. But its quite easy to get false-positives around signals only to find that they can't complete a task without handholding.
