Please, some help with the following assertion violation

Comments: http://rise4fun.com/Dafny/jsv2 In this case the induction hypothesis does not should be applied, but apparently it is applied, though one of its preconditions is violated. I know that there is a simpler proof of the lemma, but I would like to know why this exactly works.
