The edits were only approved because a user with edit privileges clicked "improve edit". When this happens, the Community user gets the credit for approving the original edit because only moderators can unilaterally approve (or reject) edits. The reviewer's own edit is the one that comes immediately after.
You can see the review history of an approved edit by clicking "edit approved". You will see something like this:
Reviewer reviewed this X hours ago: Edit
Community♦ reviewed this X hours ago: Approve
In this screen, the reviewer who decided to "improve edit" is the one listed as taking the "Edit" action.
Community may take credit for rejecting edits when a user chooses "reject and edit". Here's a recent edit I rejected and edited. You'll see something like this:
Reviewer reviewed this X days ago: Reject and Edit
Community♦ reviewed this X days ago: RejectThis edit did not correct critical issues with the post - view the revision history to see what should have been changed.
