It seems based off this comment:

You know, the more I think about it, the more this video seems to me to imply the opposite of what is being claimed here.
Fr. Chazal is asked if Vigano was re-concsecrated, and he says "the necessary has been done". Well, what does the resistance think is necessary in every case of modernist holy orders? They think an investigation is necessary; they do NOT think re-ordination/consecration is always necessary. This was stated emphatically by Bp. Thomas Aquinas, as quoted earlier in this thread. So it makes more sense to take Fr. Chazal's words to mean, "The necessary has been done, [which is to investigate the validity of Vigano's holy orders, which has been done]"
Furthermore, the refusal to answer implies that Vigano was NOT re-consecrated. Think about it. Vigano is a diplomat, and as such he doesn't want to offend trads. Being consecrated sub-conditione wouldn't offend anyone. The sedevacantists would think this was necessary anyway, and the non-sedevacantists could just be told, "We figured his validity was a bit shaky, so we did it again just in case," as has been done with numerous priests in the SSPX who came in from the Novus Ordo. No one would have any objection that I can think of. Even the conservative Novus Ordos wouldn't care all that much either; they know and care very little about things like repetition of sacraments that imprint a character, or the validity of holy orders.
Not one person would object to Vigano receiving condition consecration.
On the other hand, sedevacantists would have a major problem if Vigano had declined to receive conditional consecration, and that seems to be the position Vigano has been wooing recently. So it seems Vigano is trying not to get on that group's bad side by saying he won't be re-consecrated.
What other possible reason could there be keep the re-consecration secret? To avoid putting a target on Vigano's back? Vigano has been putting targets on his own back for the past five years. He obviously isn't worried about that.
The only explanation of this that makes any sense to me is that there was no re-consecration.
