No, I think it's the "div.post div.quote div.source" bit in the section labeled "Quote Post;" the coding in that section also sets the font and size of both the quoted text and the source/commentary beneath it. It looks like the "block quote" instruction applies to block quotes in regular text posts, so any time Frank quotes someone mid-post it should align right as well. (Except, looking back through his posts, it doesn't! Probably bad coding on the part of the template-maker -- there's probably another instruction somewhere else mistakenly overriding the block quote instruction for text posts.)
