The two example classes are used exactly the same way, and don't show the differences between them. How about a simple change like:

Replace: 
"""If the class defines
:meth:`next`, then :meth:`__iter__` can just return ``self``"""
with
"""It may be convenient to define :meth:`next` in the class, and have :meth:`__iter__` just return ``self``;  In this case though, the object can be iterated only once."""
