THIS^. He's saying we must be in "union" (whatever that means) with our NO bishops but must remain faithful to Traditional doctrine. THAT is at the heart of the problem. We do not have the same doctrine (and worship) as our friendly neighborhood NO bishop.
One of the unintended consequences of being a schismatic is a false comprehension ecclesiastical of reality. I know because I used to have the same erroneous mindset. You imagine that everyone in the "Conciliar Church" is a modernist heretic, and think refusal to be in union with the Church is a mark of orthodoxy. Nothing could be further from the truth.
What showed me that the mindset is false is experiential knowledge. Without that, I would probably be as blind as you are to the reality.
