See, for me, DADT refers to the relationship style someone I used to date had; his girlfriend knew he saw other people but being confronted with it in any way was a betrayal. This meant, theoretically, that if we had a date planned and she wanted him for something, he couldn't say he was busy because there was nothing he could be busy with that sh couldn't attend and she was used to him cancelling anything he had planned for her needs anyway. This meant that we would never be able to develop the trust and mutual respect necessary for me to build a committed romantic relationship. I would never feel valued enough. It certainly prompted me to adjust my views somewhat about my relations with metamours and what is realistic over the long term if you want to have long term polyamorous commitments.
What you describe just seems to be minimal sharing of details rather than a DADT.
