Then we can abbreviate each and every x > 0 by (0, oo).
 Your "abbreviating" is a quantifier shift.
Making it less visible doesn't make it prove anything.
My theorem: X is left-hand side of every x > 0 <==> X is left-hand side of (0, oo).
Find a counter example or accept it.
If you believe it can be interpreted as a quantifier shift, then note that not every quantifier shift produces a wrong result. Example: see above.
 "Abbreviate" rock.paper.scissors and
you get wrong answers.
That method is unreliable.
Don't waffle, do what is usual in mathematics: Show a counter example for my theorem.
