He certainly was! I was able to dig up this little gem from his testimony at the trial:
In the proceedings he was asked to spell out my name for the court reporter, and he misspelled it as “Marrti”. I do not think this was a mistake in transcribing because my name was written correctly elsewhere in the transcript. Satoshi could spell my name! Craig Wright also said I was Norwegian but I am Finnish. I emailed Satoshi from my addresses ending in .fi. In one of the exhibited emails I even gave him my street address in Finland.
Note: The "proceedings" mentioned above refer to an earlier CSW trial, the Kleiman proceedings.
