Yes, but it doesn't really matter because nobody can anything about it. The self-custody aspect reigns when you use Bisq. The problems arise when you use any service that takes full control of your coins.
So, if someone uses Bisq, can they change their coins and at the same time kind of "wash them out" and make them "clear"? Sorry for my question, but I don't know much about Bisq (besides the basics), although I'm very interested in joining and starting to do more trades there.
