I'm not sure that's right, method chaining is just immediately acting on the return of the previous function, directly. It doesn't pass the return into the next function like a pipeline. The method must exist on the returned object. That is different to pipelines or thrush operators. Evaluation happens in the order it is written.

Unless I misunderstood the author, because method chaining is super common where I feel thrush operators are pretty rare, I would be surprised if they meant the latter.

They cite Gleam explicitly, which has a thrush operator in place of method chaining.

I get the impression (though I haven't checked) that the thrush operator is a backport of OOP-style method chaining to functional languages that don't support dot-method notation.
