Garth,
Cool video! It confirms how to pronounce "Ciöcc" properly.
Obviously the frame was already damaged in some way, or the repair wouldn't need to be done. As Brian has clearly explained, it does take more heat to disassemble a brazed lugged joint than to assemble it. I'm sure a builder as experienced as Pelizzoli would take care to use just as much heat as needed, and no more. Even so, it's possible (maybe even likely) that the tubing was slightly affected by the additional heat.
It gets down to which damage you want to live with, and the owner and repairer decided that possible heat damage was less of a problem than whatever other damage already existed.

In this video, it sure takes a lot of heat to get the old headtube out. Does that amount of heat exceed the amount that was needed to braze the original? The top tube was totally glowing red hot when he was done, Did the frame get damaged in the process?
