I'm genuinely surprised because I would have assumed NordVPN keeps user activity logs regardless of what they say (what all those services say, really).
2) All the advertisement bluster in the world melts away at the arrival of the first subpoena, search warrant, or national security letter.
I'm not saying that there must be no NordVPN logs, but I am saying that if they existed and they were subpoenaed, it would be really, really surprising if Nord didn't immediately turn them over.
