Sure, it is possible, as you just proved yourself :-)
Mount will mount on top of an existing mount point.
Anything "below" it will become invisible until the
corresponding u(n)mount. There is a special filesystem
which allows the lower filesystem to show trough the
mounted filesystem and is still accessible. I forgot
what name the filesystem type was (nullfs?), though.
Browsing through the mount_* manpages will help... :-)
