When you issue the rm command, the actual function that gets executed is unlink. From the man pages:

"unlink deletes a name from the filesystem. If that name was the last link to a file and no processes have the file open the file is deleted and the space it was using is made available for reuse.

If the name was the last link to a file but any processes still have the file open the file will remain in existence until the last file descriptor referring to it is closed."

If you think of rm as a synonym to unlink, then this makes better sense. Show the client this and they should be able to understand as well.
