You are right, I should have rather tested it:
Evaluating library mylib.el:
,--------------------------
| (defvar mylib-bar "X")
|
| (defun mylib-foo ()
| (print mylib-bar))
`--------------------------
after opening buffer local-var-test.org:
,---------------------
| * 1st Level
|
| Lorem Ipsum
|
| # Local Variables:
| # mylib-bar: "Y"
| # End:
`---------------------
does not change the expected result when doing
,----------------------
| M-: (mylib-foo)
`----------------------
with point in buffer local-var-test.org:
,----
| "Y"
`----
