​Or, "The restriction that variables must appear only in the result list or
HAVING clause applies to the query level to which the aggregate expression
belongs." (I would consider emphasizing the word belongs).

Really, just adding the word variables - "The restriction about variables
appearing only" - would make it technically correct.

Your proposal of only changing "about" to "above" makes it grammatically
wrong and fails to fix the underlying problem. "about" it is right word
but the sentence fails to provide "what", what must only appear in the
result list or having clause?

A meaningful example might help too - I'm having trouble imaging when one
would choose to write a subquery whose effect would end up being treated as
part of the main query.
