All fine. Now do you mind to explain why you want to do this ?

"/home" is an absolute pathname and means that the object "home" is 
directly in /. /home as a directory does not exist any more after it as 
been moved/renamed as /data/foo, so you would not be able to put 
anything in /home.

Why then don't you store the data files in a common location outside 
home directories and leave the home directories in their respective root 
filesystems, as already suggested by others ? That would avoid 
scattering data files across all home directories.

A file is opened when it is currently used by any local process. The 
current working directory counts as an opened file. Files in a user home 
directory may be opened even if the user is not logged in, for instance 
if a web server with user home pages enabled is running and the user has 
set a home page.
