You have a good memory. Only for the record, the exact quote reads:
It is also possible for the directory hierarchy to be split
across several devices. Thus the system can store a directory,
and all [files] and directories lower than it in the hierarchy,
on a device other than the one on which the root is stored.
In particular, in our own version of the system, there is a
directory "/usr" which contains all user's directories, and
which is stored on a relatively large, but slow moving head disk,
while the othe files are on the fast but small fixed-head disk.
