While I am sure there are faked videos out there somewhere I have personally performed multiple non-fake multi-board breaks as have many other people. Generally there is one "trick" though: pencils or small wooden dowels are used to space the boards apart which makes the stack of boards weaker than if they were stacked without spacing. I'd argue this is an allowable aspect of showmanship in that five separated boards is cooler looking than two or three stacked without spacing!
