This is the first time I’ve ever seen that suggested, but it does make a bit of sense. That said, a scrivener was an occupation: a professional copyist or clerk, like Bartleby the Scrivener. It’s from Old French escrivain (same meaning) which is in turn from Latin scribere (“to write”), which might be from proto-Indo-European “skribh-“ which is a stem for cutting or separating.
