Yup. "Math" for Lacan is employed in an entirely different context than the usual context. It's moot whether or not he gets those rules "right".

I think Sokal's after more than nitpicking - he's objecting to the entire movement, especially its application to science. He and a mathematician co-wrote a book (which I haven't read, and don't intend to) in which he criticizes the epistemological attacks made by Kuhn, Feyeraband, etc. It's really a quite separate issue from that parody article tho' - which makes me think he did it just to promote himself.
