The point was, RETURNS returns 1 while RETURNS SETOF returns 0 .. n.

no RETURNS return "VALUE" (it is not a row) .. and in combination with SELECT - value will be a row. RETURNS SETOF returns rows

I intentionally excluded the data type of what is returned.
1 "VALUE" vs 0...n "VALUES"
Do you still fail to see the point 1 "VALUE" is special in the context of what a function returns?
