Those don't even look like they were signed by the same person. I haven't tried him TTM because there's so much speculation about them being secretarial. The top one looks similar to other TTM posts (which again are iffy), but that bottom one is really fishy looking to me. But I'm hardly an expert here, so it only really matters if you're happy with what you got.
^^I agree. Look at the Ds in the first name. They're signed two different ways, which usually means two different people.
