It's strictly my opinion based on a bunch of suppositions:

1) That the Waterford website description is correct about Frank Brilando advocating the silver brazing.

2) That Frank was an engineer and would find a technical basis for this "innovation" and extra cost.

3) That Schwinn was fanatical about frame integrity and stood behind a 100% frame warranty. The dealer I worked for was edgy about selling any lightweight but had greater faith in the Paramount than say a PX-10 or Raliegh International (not that this concern was rational).

4) Based on my experience, I didn't know that a single silver alloy could both braze a lug and build up a fillet. When I designed the lugged driveshaft, the lug/tube gap had to much smaller than if it had been brass brazed. I also remember Redcay talking about using a different silver brazing alloy on his dropouts as opposed to the lugs.
