Hmm, this threatens to get a little philosophical, but that seems to
contradict earlier text in the same node:

       Here is how lexical binding works.  Each binding construct
    defines a “lexical environment”, specifying the symbols that are
    bound within the construct and their local values.  When the Lisp
    evaluator wants the current value of a variable, it looks first in
    the lexical environment; if the variable is not specified in
    there, it looks in the symbol’s value cell, where the dynamic
    value is stored.
