If $back_home is not defined then the command cd ${back_home} would evaluate to just cd (since "back_home" would evaluate to nothing). This would indeed take you "back home" (as in to your home directory - since cd with no arguments is equivalent to cd $HOME).
If you want to test if a variable is defined, you should use the test command!
