typo in batch-decision?

here https://uhm0pk9ugygnd65mwv9ya7r01euvaeknxz28c.julianrbryant.com/sample/batch-decision/
myJob.xml says: < next on="foobar" to="step3"/ >
but the text says: 
Decider is always returning the value foobar which forwards the execution to step2

shouldn't the xml also say to="step2" ?
