The context right before he said that was that platforms are the interesting things, not languages. He's a Python user at work so he's getting his daily dose, but mixes things up at home.

He then goes on to say some of the quoted stuff about punctuation/structure. I took it as programming languages in general aren't an interesting topic to him, but Python caught his eye and actually interested him for the educational value.

Zed can obviously speak to that better than I. I just pretend I know how to interview and write :)
