Correct, and /usr/bin was a common writable directory intended to permit users to share their private programs.
Official UNIX programs have been in /bin only these days.
BTW: Man pages for the shared private programs from /usr/bin exist because Stephen Bourne wrote a cron job that every night checked whether a new binary did also result in a better/newer man page. He explained that on a talk on a Sun User Group meeting in 1990.
When /usr/bin has been kidnapped by the system, people invented /usr/local as an "escape" and soon admins kidnapped /usr/local .....
This was the reason to invent /opt in 1987 in order to break the chain of similar mistakes.
