He probably means something like the following:

Assume that /tmp exists as a separate filesystem.
With /tmp unmounted create a lot of files in the /tmp directory (those
file end up on the root filesystem)
Mount /tmp.
Now the files that were previously created in /tmp are shadowed by the
/tmp partition and not seen be ls or du.  They do still use space on /
though.
