That actually the original reason from /usr split from 1971.

When the operating system grew too big to fit on the first RK05 disk
pack (their root filesystem) they let it leak into the second one, which
is where all the user home directories lived (which is why the mount was
called /usr). They replicated all the OS directories under there (/bin,
/sbin, /lib, /tmp...) and wrote files to those new directories because
their original disk was out of space. When they got a third disk, they
mounted it on /home and relocated all the user directories to there
