And again, that refers to CAPTCHA used for creating new accounts, not
the one under discussion.
Um, no it doesn't? It referred to *all* CAPTCHAs.
Really? It refers to "the CAPTCHA", singular, when the CAPTCHA under
disussion was that for sign-ups. It also quotes:

I would recommend you read
<https://www.mediawiki.org/wiki/Extension:ConfirmEdit/FancyCaptcha_experiments>
which has some more details.
So two things were disabled, and a change was noted. We don't know
which of those two things caused the change. We have no evidence as to
whether or not disabling the CAPTCHA *just* for (signed in) editors
saving an edit would have a negative effect.
