You can make that happen:
# cd /usr
# mount /dev/<blank> /usr
# vim
vim: not found
# ls /usr/bin
ls: /usr/bin: No such file or directory
# ls bin This will show the contents of /usr/bin before
the mount, because it looks in "./bin", and
"." is on the original /usr, not the new one.
# bin/vim will find bin/vim
# pwd This is both true and not true. The current
/usr/bin directory is /usr/bin, but you won't get there
if you cd to /usr/bin.

Well, without knowing exactly what you did, we can't say how you got
those results. But I suspect something like the above.
