I think he's referring to the time when desktop Linux was competing against the likes of Windows 98. At that time, it was common for household PCs to be multi-user because one computer was shared by several people in the house. But with Windows 98, there was no protection between users; anybody using the computer could read anybody else's files. Even if you didn't have an account on the computer, you could just press [cancel] at the login screen and have access to the computer. User accounts on Windows 98 were only for the convenience of having different desktop settings, there was no concept of files being owned by specific users.
Linux was a lot different at that time, in that it actually had a concept of users owning files. If you wanted to access another user's files without their permission you had to jump through more hoops like booting into single user mode.
single user == root only. While linux has a single user mode, it is rarely used. Certainly not everywhere "excluding some exotic and super fragile setups you might see in .edu networks"
