The view objects aren't sequences. od.items() and od.keys() implement Set. od.values() doesn't even do that much, only implementing __len__(), __iter__(), and __contains__().
The glossary implies that you should use "reversed(list(view))". [1] More information on mapping views is located in the docs for collections.ABC and for dict. [2][3] The source for the Mapping views is also helpful. [4]
Keep in mind that OrderedDict is not a sequence-like dict. It is essentially just a dict with a well-defined iteration order (by insertion order). [5] Just like its views, it should not used as a sequence.
