Otherwise, it will assume they're pipes between commands.
To print them one per line:
Changing the special IFS variable to "|" makes unquoted strings split on |, so $STR becomes a b c d e which, fed into printf "%s\n", prints each string on its own line.
Then you set IFS back to normal because you probably don't want it as | all the time.
