The second pairing of ODF files in auto-mode-alist is not with
doc-view-mode but with doc-view-mode-maybe, whose doc string says
"Switch to `doc-view-mode' if possible. If the required external tools
are not available, then fallback to the next best mode." In this case
the next best mode is archive-mode, due to magic-fallback-mode-alist.
That's why the first pairing is dispensable.
