I would think the claim refered to the specificity of how to select links etc. I think selenium predates jQuery, which as one of the first frameworks used CSS selectors to address DOM nodes. You typically don’t want very specific selectors for your links and buttons to click, so you don’t have to change the test every time you update the HTML code. As I remember the selenium extension produced very specific code there. But as you mentioned, there is more than one way to work with the generated code.
