Typo in course FHS /lib and /lib64 ?

Hi,
In the page https://trainingportal.linuxfoundation.org/learn/course/essentials-of-linux-system-administration-lfs201/linux-filesystem-tree-layout/linux-filesystem-tree-layout?page=10

It's written:
$ ls -l /lib*

rwxrwxrwx 1 root root 8 Apr 23 2020 /sbin -> usr/sbin
lrwxrwxrwx 1 root root 7 Apr 23 2020 /lib -> usr/lib
lrwxrwxrwx 1 root root 9 Apr 23 2020 /lib64 -> usr/lib64

I don't understand why ls return /sbin in that case.
I think it is a typo, if not can anyone explain me please.
