Also note, that after Uncle Bob's refactoring, you now have six additional functions floating around, which may or may not make sense outside of the context of their original caller. This can make the API surface of your class (even if it's just the internal one) harder to grasp and it invites other devs to reuse code that was never intended for reuse, creating unintended couplings. That's mainly a problem for languages that don't allow nested functions though. But in Java, I am sceptical of excessive function creation for the sake of self-documenting code, unless maybe it's in the context of a command pattern, where the whole class only has one obvious function anyway.
