The requirement to pass the text through at least two detectors applies to either post. In both I got 100%. I ran that post through a third one, sapling.ai: Fake: 99.9% Is not three 100% results enough?
I also agree with the reason you tagged him. He was tagged with absolutely authentic evidence of tagging. Although sometimes many people make mistakes in tagging, I checked it and the tag you gave is correct.
You gave the tag after checking three posts, but this tag is a warning. If someone posts with this kind of I, then I think one or two posts are enough, not three. And for this, he has been given a warning tag. If he corrects himself from here, then of course it is good.
