Yes. Gavin assisted Economist's write up:

"Still, as far as we can tell he indeed seems to be in possession of the keys, at least for block 9. This assessment is shared by two bitcoin insiders who have sat through the same demonstration: Jon Matonis, a bitcoin consultant and former director of the Bitcoin Foundation, and Gavin Andresen, Mr Nakamoto’s successor as the lead developer of the cryptocurrency’s software (he has since passed on the baton, but is still contributing to the code)."

That's some crappy wording. We are going all these lengths (crypto and stuff) to then be uncertain: "seems". "at least".

Concrete proof is required.
