That's better, but it's still not great. Once you've moved from A, B, and C, to D, E, and F, if you then start to consolidate D, E, and F together, although a third party couldn't definitively link A, B, and C as all belonging to you, they could get a pretty good idea which they may be able to combine with other information.
Yeah, that is truism. As it was stated A, B and C should never be consolidated either directly or via any mediators including addresses user owns. I think the best way is to continue consolidation on different addresses or spend UTXOs not mixing them.
