This very well could be.
As someone else mentioned, rather early on Q said in a post that they would leave for good. But they continued posting for a couple years. Leads one to think that either posts don't go in chronological order, or someone else took over posting in place of Q, or any number of other options.
It's looking mostly likely that the posts do not go in the order they were made. And remember, Q never numbered the posts. That was done by those who set up sites to store the posts for future reference. We may be putting undue importance on those post numbers.
And then I solved the captcha on my first try-lucky day for me!
