Yes, it is confusing - I use Tree Size and examining those folders in the past has given me a headache - I was getting problems with the size of my SVI folder growing uncontrollably with Malwarebytes (happily resolved with later versions of the software) and making sense of what was going on was difficult. My main concern is that, when I have created a Restore Point using WRAIO, I've not been able to restore from it, so I don't trust it. By and large, Windows 7's inbuilt restore process has always worked for me. But it's always belt and braces for me - a combination of regular bootable backups and restore point backups to external detachable media using Casper 10 alongside registry backups in WRAIO and restore point creation in Windows.
