Problem is that if you get thirsty- it is too late. You are de-hydrated and will pay for it in a lack of performance.
Despite posting the OP I follow these same guides and will continue to do so. I was not aware of the danger of overloading which is why I posted the reference but I am still a bit more worried about waiting too long to drink. I don't think I overload, but I do keep up regular slugs to make sure I don't dig myself into a hole. And I always carry a second bottle on rides over 15 miles (which is almost all).
