I've never heard this distinction between adaptive and responsive. The article claims that responsive layouts are series of liquid layouts while adaptive layouts are series of static layouts. I was under the impression that "responsive" refers to all usage of media queries to swap layouts, and it just so happens that most of the time liquid layouts are used.

I haven't heard of adaptive before either, but I kind of like it. The original book on responsive design spent a lot of time talking about how to correctly make liquid layouts, and heavily advocated for their use along with media queries. It wasn't until Bootstrap that responsive design also started meaning static layouts with media queries.
