This is correct, there is an article (I think on the semianalysis) that summarises the process - they are using multi-patterning as TSMC did with their N7 7nm process. The real shocker is that they've been pumping out 7nm commercially since at least a year, which is a feat that most thought was still a ways ahead. It means that they are far more capable than previously thought.

    I don't think we can conclude it's an intelligence failure. Perhaps the intelligence community already knew?
