This means you misunderstand dynamic scoping or the meaning of
"default-" in `default-boundp` (it has nothing to do with let bindings
but is only concerned about buffer-local or not).
If you disregard lexical scoping, there are kinda to dimensions to
locality of variables: there's the "let" locality and there's the
"buffer" locality. They can be combined. `default-boundp/set-default`
only differ from `boundp/set` on the "buffer" dimension of locality.
Lexical scoping is yet a different beast because lexical variables have
fundamentally no name, so a lexical binding of variable `foo` has no
relation to what `boundp/set` see when passed `foo` as argument.
