I think the idea is that instead of running GCD once at the end of (B2=B1*100) it could be run multiple times as B2 is expanded, for example run it 10 times at successively higher B2 values...

Presumably on the assumption that stage-2 is done to incrementally-larger bounds as the stage progresses. Stage-1 bounds can be repeatedly extended from a previous result, but I'm not sure if stage-2...

Early versions of Prime95 had P-1 bugs so there's lots of P-1 efforts from circa 2000-2005 that missed lots of factors.

But aside from that, there are still a (small) number of P-1 failures still...
