For extremely large amounts, larger than other users contribute combined, Wasabi has to break down your amounts into smaller amounts that actually can be mixed. In that process Wasabi wallet correctly tells you that you haven't yet achieved meaningful privacy.

For smaller users, Wasabi can much more easily achieve meaningful privacy because other users have contributed more funds to the coinjoin than you have.

Yes I understand broadly how it works, but the point was just to say that this mix did not actually made 610 BTC "anonymous with a single tx", it's much less.

Many more rounds are needed to achieve acceptable privacy for these big amounts break enough links and achieving a big enough anonset.

Ah, sorry, I didn't see what you were replying too.

Yes, I agree that the claim overstated the privacy they got. But it's not as much as you might think: since there were _two_ big inputs, and those inputs do appear to be from different people (they're Wasabi coinjoin outputs), it is correct to say that they got some privacy as it's not clear for any input which person they came from. Depending on how you want to define it, the k anonymity set is somewhere between 1 and 2, which isn't bad for that amount of money.
