In the new(ish) review (for example, for low-quality posts), what happens behind the scenes when I click the "Looks Good" button?
Is it just equivalent to following a link to the post in the old review, and then doing nothing with the post?
My understanding is that doing that just caused the system to record that the post has been reviewed by one (more) user than it had before, and that when a post is reviewed by 2 (or more) users--actioned or not--it is dropped from the review queue.
Or does it actually "counter-flag" the post, such that any existing flags are indicated (to moderators and 10k users) to have been considered invalid by one (more) user?
Or does it do something else altogether?
