Are you sure that you don't just see the global binding of that
variable?

Please note that `make-variable-buffer-local' is a function (in contrast
to `defvar' or `defvar-local' which are macros), so the argument
(expression) is evaluated and should return a symbol.  When you want to
specify a symbol quote its name: 'SYMBOL.
