Just the variable scope.  Once you have run:

     1> case [] of [] -> X = aaa; X -> ok end.      
     aaa

The variable X is now bound:

     2> X.
     aaa

If you forget it first:

     3> f(X).
     ok

Your second example will work:

     4> case bbb of [] -> X = aaa; X -> ok end.       
     ok
