His intended use of meta is wrong.

So is your description, Meta is an ancient greek preposition that in English roughly means a concept that is an abstraction from another concept (though originally in Greek meant "after").

It is also used commonly to mean something that is knowingly circular or self-referential "That film director doing a movie about film directors was so meta", I don't like this usage but it is common.

In either case your usage is considerably narrower and not at all the standard usage.
