"That's where it's going to come back and bite you in the {@$$}.) If someone has been admitted into what they truly regard as an authentic link, I judge that we are not entitled to have formal connection to them. You could lie to me and say, "Oh, I now don't think they were real," and you might fool me into thinking that's the case, but you're stabbing yourself in the back if you try that. One shot at the Real Thing per incarnation: That's the rule."
That makes perfect sense to me. One can only assume that someone would only go as far as the Probationer Oath if they really did believe they were getting into the real deal. If they didn't think so but signed the oath anyway, well then, that raises a whole bunch of other red flags!
For interest's sake, what is the origin or the reason for the one chance per incarnation rule?
