That would be somewhat reasonable if it were just an implementation detail. But unfortunately, it's not just an implementation detail. When a filesystem has data to write and runs out of hard drive space, it overwrites the data which was flagged for deletion. But when a web 2.0 company has data to write and runs out of hard drive space, they buy more hard drive space, usually automatically.
It probably is an implementation detail. I'd bet you 64 days is time is takes for all their backups to be rotated.
Not that I think that's legitimate! Implementations can be changed, just like you could write a filesystem that shreds files when they are deleted.
