Seems like a low quality article to me. 1. If you have leaked data to an unencrypted partition, then simply deleting it will not hide it from forensics experts. 2. There are many vectors in which an _application_ (because that is what we are talking about) can leak data to unexpected locations. This isn't even one of the more subtle ones, in fact it is expected, and probably present on every major os. 3. The article baits fear mongering and conspiracies.
