Precisely.
It's also possible that the analysts are fooling themselves as they assume quite a bit about why Q is writing. For example, you will have much less variation among military message traffic than you will between blog posts. Q's first posts were made very differently whereas the latter posts began to take on a more traffic-like structure, which is designed to create uniformity and consistency in writing.
If you'll recall, that was also around the time the first tripcode was 'broken.' Matlock. Which many associated with being the ambassador Matlock between U.S. and Russia at the time.
Q intended for that first trip to be broken and there was a period of time where identity needed to be verified and continuity maintained.
