As explained in the patch description, it isn't about the precedence, but about grouping together the options that have something in common. In more detail, --cached and --untracked have something in common, i.e. they both leave git-grep in the usual state, in which it treats the directory as a local git repository, unlike --no-index that makes git-grep treat the directory not as a git repository.

Please note this isn't a link, it just mentions the operation. Though, I agree that rewording it a bit might be beneficial.

In general, not addressing the user/reader directly is preferred in technical documentation, because it eliminates the possible element of persuading the user to do something. In other words, we should be telling the user what our software can do, instead of telling the user what to do.
