Yes, they're both issues, but the NREC is the main issue. I think the NREC is probably invalid, whereas I think the NRPO is doubtful at best.
The SSPX is now bringing in NO bishops without consecrating them in the Traditional Rite, so there will be more and more invalid priests there.
Yes, the SSPX has also been allowing priests to serve at their chapels who are ordained in the new rite by bishops consecrated in the new rite ... without requiring conditional ordination. It's just a matter of time before we have that "Bishop" Huonder ordaining priests for them also.
That's actually THE MAIN reason that The Nine broke from SSPX in the early 1980s. For the MOST part, SSPX asked priests to be conditionally ordained. But in the case of a "Father" Stark, Mr. Stark refused to submit to conditional ordination, and Archbishop Lefebvre allowed it to slide and insisted he be allowed to help with SSPX chapels. So this Mr. Stark's stubbornness led to the expulsion of some of the finest and most talented priests the SSPX has ever had. Most people have the incorrect perception that the break was about sedevacantism, but one of The Nine told me personally that not all of The Nine were even sedevacantists originally and that it wasn't the motivating factor. Acceptance of NO annulments was the other issue. On that, I actually agree with +Lefebvre. SSPX had no actual authority to impose its view of any given annulment on consciences. At best, they could offer advice: "We believe that your annulment is illegitimate or doubtful at best. If you carry on as you are, you're putting your soul in grave danger."
