He definitely is not using 99% pure silver for reasons you posted, and for sure not doing this with a simple pencil torch, especially considering butane or even propane can only reach a maximum flame temp of just under 2000F without the use of pure oxygen. Silver solders with melting temps closer to 1200-1300F are only ~50% silver with the rest being copper and tin. Brazing at that temperature on a brass hookah with a pencil torch? Yeah, good luck with that.
