Considering the fact that I personally was one of the trainers affected, and I'm not currently still suffering from having the translucent body of a Reuniclus, I would say they did change back, yes.
But no, not necessarily. The year before that was an entirely different kind of occurrence...it involved two groups known as Team Magma and Team Aqua seeking to harness the power of two legendary Pokemon to reshape the regions in their images. Obviously though, that didn't work out.
