Ady created the Alderaan destruction video as a joke because he imagined the worst thing anyone could do is edit Jar Jar into A New Hope. He figured he would make a joke video. It was a joke, NEVER considered to be in the final edit.

Seriously? I thought I remembered him saying he didn't put it in the edit because it showed Alderaan's destruction as rather slow which didn't fit Obi-wan's description of it as instantaneous.

Well I'm glad to know he never actually thought of putting that in ANH.
