I found an old post of mine on the same topic, written much closer to the time with more details and, no doubt, more accurate than my memory is now of the conversation. Maybe they asked multiple similar questions.
The point, though, is about whether the focus at the time of departure from the Witnesses is on belief in God and the bible, or acceptance of the organisation.
For context, I was a third generation JW, a well-liked goody-two-shoes, self-righteous prick and good public speaker who had recently stepped down as an uber-MS and stopped going to meetings. The DO had recently left (that was Joe) and two COs had recently been DF'd while on our circuit.
For what it's worth, this is a lightly edited excerpt from 13 years ago:
The question they asked me was something like: 'In your opinion, do the Witnesses present the truth, but that truth isn't for you; or, do you believe the Witnesses do not present the truth'? I replied that I'd given that some thought and checked the dictionary definition for heresy and that seemed to describe the first condition they described. I'd also checked the dictionary definition for apostasy, and that seemed to describe the second condition.
I said that I didn't think that either condition described my position, but that I was acutely aware that my current thoughts were probably wrong and that I couldn't and wouldn't presume to trouble others with it. 'At the end of the day, I'm not sure where I'm at in regard those very serious positions you describe, but I remain absolutely dedicated to truth and goodness. I just don't know about those sorts of really big questions at the moment' (and what's wrong with any of that from the JW point of view?).
I wasn't subject of any judicial process at all. The point is that you can leave without being DF/DA, if you no do not profess a position against the Society. Private non-belief or un-certainty are fine. I used to assist in the shepherding of 'inactive ones' (ie: those who'd left on their own terms and weren't DF/DA), some I had met on the doors and had no idea had been JWs.
The attitude of the elders seemed fourfold:
1) calling was a duty,
2) it was just a matter of being nice and letting them know they could come back,
3) it didn't matter what sins they were committing (de facto relationships, smoking etc), and
4) it was easy field service hours, often complete with tea and cake, so long as they weren't identifying as JWs.
