Age of backlinks and TLD has always been a factor. But now i think google is not confident of data they have for the last 8 months or so. They have it in different datasets. They have always kept things with a timestamp, whether it is a TLD, a page or a backlink. But this time this is all messed up. So they are showing more confidence in what they had 8 months ago.
It may continue while they sort this out by holidays!
