I'm not sure at all, and this is the core of the debate. It's really a co-ordination problem: boycotting the triennial proceedings would require a unanimous action, in the face of increasing damage by 1201. So when I say "it became clear", it's not so much that the strategy was clearly better, but the calculation between a principled boycott and pragmatic involvement shifted.
