The setting only affects expressions that are inside the bounds of the let expression. In computer science jargon, we would say the binding of a symbol is visible only in functions called in the let form; in Emacs Lisp, the default scoping is dynamic, not lexical. (The non-default lexical binding is not discussed in this manual.)
