We're not seeing any else, e.g. laundering through another exchange, splitting into different accounts, automating the liquidation of tokens to ETH, off loading ETH into a cold wallet etc.
The on chain activity makes this look like an individual who did not prepare extensively before doing this or doesn't have the skills to use automation/operational best practices
EDIT: first outflows from 0x59abf3837fa962d6853b4cc0a19513aa031fd32b have started, they still haven't liquidated all their PAXG, a stable coin pegged to gold, unclear if it's freezable.
They were able to liquidate all of their USDT except 4M on avalanche, and all of their usdc both of which can be frozen. Dai is a usd pegged stable coin that can't be frozen, they have nearly 1% of it. Note that Dai is heavily exposed to USDC so authorities could pressure USDC to destroy Dai
