First of all SW coordinator is blinded run over tor so even if Samourai can track xpubs they don’t know entities ip and even if they do they have no idea about what happens post mix txns.
For equal outputs to exist there will be change and coordinator is blinded (soon decentralized) It doesn't know the links between a coinjoin's inputs and outputs. That was one of the major goals of the zerolink framework. Also doxxic change is completely unaffected by mixes since it has never been mixed.
Every SW user knows exactly what to do with that doxxic change so there is no combining with other doxxic change that didn’t come from the same source.
The Tx0 makes all your UTXO's share a tx hash, which prevents them from mixing with each other, preventing an "accidental" Sybil attack from entering a large amount of BTC, Samourai separates the coordinator fee in the Tx0 no fee flagging in the fee addresses. Every communication between Alice and the coordinator is made with a different Tor identity. It's transparent for the coordinator if one of the messages is actually sent by Bob, so when Alice sends her clear output to the coordinator it's made with a Tor identity different from the Tor identity used to submit the input and the blinded ouput. Who is using this Tor identity is transparent for the coordinator. It’s two separate Tor identities. This was even in the original zerolink docs IIRC.

So once coins are mixed, they are segregated and can't "accidentally" make their way back to unmixed section of wallet. You have to manually generate a receive address and send from postmix to get utxos back there, which obviously you shouldn't do. This is the only way to have true ZeroLink, where a user can't spend mixed and unmixed together. SW doing ZeroLink original spec, whihc is simultaneous denominated pools, max entropy mixes for the number of inputs/outputs, never 2 or more same previous tx in a same mix, and unequal amount coinjoined spends post-mix if the user chooses.
So no they will not be able to demix everyone. If that happens then why wasabi users were arrested but not sw or sparrow?
