Doesn't seem like such a great idea to me. It forces you to pay at each iteration of a loop when you could pay once to ensure that your ending zip iterator is formed from the correct position in each sequence. In my opinion the zip_iterator documentation should be improved (quite a lot) to make the requirements more explicit. For iterators over a container, that is indeed true. In which case, surely it would be better to provide a constructor which calculates the minimum distance rather than relying on the user to remember to check beforehand.
