So, I just finished, and the main takeaways are that it's very clear he does not regard Jorge as a legitimate pope, or at the very least considers him to be highly doubtful, based on the notion that the 2013 election was illegitimate. He rejects the notion that a faulty election would be "sanated" sanatio in radice by subsequent Universal Acceptance. He believes the election and/or continuing papacy of Jorge is invalid primarily due to a defect of consent or intention, along the same lines that Bishop Sanborn outlines above, holding that Bergoglio had a malicious intention to destroy the Church and the papacy, and that prevents him from exercising the authority of St. Peter. He also states that while we must "resist" Jorge, obeying God rather than man, that's not enough and we need to get to the root of the problem (after which he goes into why he believes that Berogoglio may be or is an illegitimate pope). As OP stated, he comes a hair's breadth away from saying Jorge IS illegitimate, but basically indicates that it's very possible or even very likely.
