Why does withdrawal show txhash of original deposit?

I deposited ETH in tornadocash from website, got note. Waited few days, did withdrawal on a different computer, different browser, different IP address. So no link between deposit and withdrawal, no cookie storage possible. When relayer confirmed transaction I got txhash link few seconds later, but txhash was link to original deposit with block explorer timestamp 14 days ago. Past withdrawal always had link to new txhash but this one for sure had link to the old one.

Withdrawal transaction worked but I am concerned about link to original transaction, I thought the idea of tornadocash was that link is broken and there is no record of deposit transaction for relayer when withdrawing?
