JW daughter - I see that no one answered your question, so here's the scoop:
For a time in the late 70s, early 80s, the WT Society laid down a guideline that publishers who were not baptized would be considered "upbaptized associates" and an announcement would be made to that effect so the rest of the herd would know you were "authorized" to go out in Field Service, although not formally dunked (yet). The requirement was that become such, you had to answer a couple of questions to assure the elders that you were living your life "in harmony with bible principles' and that it was your intention to become a JW in time.
If such a person got into some "trouble" which, in the view of the elders, required some judicial attention, the case would be handled "judicially" the same as if you were baptized. If they found you "unrepentant" (which is dub for "guilty"), they would announce you are "no longer an unbaptized associate."
Perhaps that is what happened to you when you thought you were "disassociated." Or perhaps I have the words slightly wrong - it's been 25 years!. I can remember when such an announcement was made, everyone at the hall viewed it as a "disfellowshipping." The average dub is often confused by the society's official buzz words, so there is always confusion. Perhaps for this reason the Society dumped this whole process after a few years, after which you were either baptized or you weren't, no in-between.
