The whole thing is very strange imo, that video only confirms that it's all very strange.
Yes, I agree, in modern times it is strange to have a group of priests (and now bishop) fighting to maintain the Faith and finding validly ordained bishops to validly ordain priests (and now a bishop) in the traditional rite.
It is very strange and wonderful! I thought some people would like to see where they were coming from on this (since not everyone knows who ordained them) and this video does show some of that.
