"Otherwise someone with a bot would just manually answer the first captcha and switch thier bot on - multiple checks are needed to prevent this." I said to recheck after "my bot" has completed quite a few posts, that would be reasonable.

The captcha was thrown because I didn't have enough reputation to make questions without a captcha. But my point is that it should not to ask the captcha if in the end your action is going to be rejected. When my question had 0 tags the site behaved properly. For 6 tags it behaved differently, first captcha then consistency check.
