There are allegations that Satoshi may have accidentally slipped up and leaked IP address that was not a Tor exit-node or other anonymous-proxy.
Could either be Satoshi fucking up and not using Tor all the time (has happened to other 'anonymous' entities) or perhaps they needed a clearnet connection for some reason and managed to use another internet connection not attached to any identifiers that would lead back to them despite that.
