Seems the community thought it was fit as an answer.
Here's the reviews:

Wouldn't disagree with that thought when viewed just from a review queue point of view(which doesn't show the others answers - but ideally you are supposed to look at other answers too).
Perhaps a custom mod flag stating 'bulk of answer copy-pasted from an existing answer' would have been a better choice. Anyway, the post is now auto protected(there are 6 deleted non-answers/me-too posts)
