Of course it does matter. A tight closeup portrait is not a macro though a number of people will call them such. It is that sort of thing that makes weakens the term macro.
Of course it doesn't matter. If its a closeup of a bug or flower then whether it is 1:1 or 1:4 isn't really relevant. But is this a macro?
