there was a time (sunos 1990's for example) where mounting /usr on a separate partition was normal.
this might have been because disks at the time were too small to install the whole operating system on one, so usr could be located on another partition.
this is also why we sometimes have a /usr/sbin and /sbin for example. so theres the binaries needed for start up in /sbin, which would mount first.
anyway i digress for reasons of providing some background.
To further digress, it also meant /usr could be mounted (read-only) and shared between multiple clients over NFS ... thus saving precious hard disk space ... (those were the days!)
