The negative ("we are not in a simulation") is the falsifiable version. It could be falsified by discovering a flaw in the simulator.
Bostrom's formulation has a properly constructed hypothesis: see http://simulation-argument.com/simulation.pdf
It can't. We cannot distinguish between flaws and non-flaws. What is a flaw anyways? That is ill-defined - we are conjecturing about what will or will not be present in a reality that we have no indication will resemble our reality.
