Yes, those death were not from N2O but from lack of oxygen (as the abstract clearly states). It turns out not breathing oxygen is really bad for you. I don't think anyone has ever died directly from N2O, unless a cylinder fell on them. (but to address the original comment, N2O should be just as effective as N2 for killing people, as would helium or any other inert gas, because it is the lack of oxygen that kills)
