Codex:

Clears the recorded edit root ID from any attachment pointing at a deleted one.

Without this, attachments created by editing the deleted image would keep pointing at an ID that no longer exists, and could later point at an unrelated attachment if WordPress reuses that ID. This only runs when an attachment is deleted for good. On sites where media goes to the trash first, attachments keep pointing at the trashed edit root until the trash is emptied.
