That's because under Unix, each line is executed by another instance of 
the shell.  And since on Unix the current working directory is local to 
the program, putting a cd on a line by itself does nothing: once the 
shell that did the cd returns you are back in your previous directory.  
Under MS-DOS that is not so.
