Thank you, and agree with hirako2000 that I was primed to believe they would actually reply like that, so found it harder to follow for that reason.
Thanks for clarifying. The interesting thing is, confusion is due to finding not too hard to believe Anthropic is audacious enough to respond publicly and include a gif.
