Wow, that is a good point. It would be interesting to know the details of that!
It could be a case of "do what I say, not what I do."
The recommended JW courtship is usually at least a year of dating and as Sam Herd said at a circuit assembly when he was my DO, "Not someone fresh out of the pool".
I remember a pioneer who had a single bible study about to be baptized. The pioneer told her, "The bad ones will try to ask you out you right away...the good ones will wait and observe." So usually even before a year or so of dating, new ones are supposed to pass a period of "observation" before they are viewed as datable. Of course, all of this is unwritten lore.
It is a case of control. The organization likes to control who is allowed to marry...those it favors get to marry, those who do not measure up to high standards are left to whither in loneliness. I'm so glad not to be part of this mess anymore.
