You do reveal new information: tx0 shows multiple payments were sent to the same user since they are consolidated before entering the coinjoin. Each of the entities that sent these payments become aware of each other as well as aware of new addresses that you own that none of them interacted with at all, which is both the doxxic change address as well as the addresses of the first equal sized output you create to enter the first round.

WabiSabi coinjoins hide all this information since every transaction is a coinjoin instead of revealing these links through the self spending tx0. Multiple payments can't be deterministically linked to the same user with WabiSabi since your inputs are consolidated within a coinjoin instead of consolidated in a self spend. No doxxic change is created either in WabiSabi coinjoins unless a whale submits a non private input worth more than the rest of the round's participants combined.
