There is only one '/', but other filesystems can be mounted on 
subdirectories, same as any *nix system.

You need to study the general concept of mounting in *nix, 
and tmpfs[1] in particular. 

   sudo mount -t tmpfs - /var

For fun, boot Knoppix (on a PC), then execute the following to 
get a clue how much fun you can have: 

   mount
   ls -l /
   man mount
   man mount | grep tmpfs
