It is more or less this. But after two conventional disputes, the alleged copyright holder cannot just claim it again. They need to go into the DMCA legal process - as so far this was just YouTube backed policy. Once a DMCA takedown received a counter-notification (disputing it), the alleged copyright owner has to either file a lawsuit, or just back out. They won’t be able to either claim the content or take it down again (unless they use shady techniques, which could get them in trouble). In a vast majority of cases, they won’t file a lawsuit, even more in this specific case of a very short excerpt, which could fall into fair use anyway.
