The short answer is yes.

The long answer is, that was one of many questions about input 
iterators that was cleared up at the Tokyo meeting in November '95.
Input iterators are queer birds, and using them (or writing them)
safely requires careful study of the requirements table and all
the associated notes.  The April '95 draft is lacking some of these
notes.
