That only applies to a subset of the rules, the ”Accounts that affiliate with organizations that use or promote violence against civilians to further their causes” part. (And seems to mean that merrely supporting an existing government or military isn't prohibited conduct, even though governments and their militaries sre groups that do, routinely, use violence and the implicit and explicit threat of violence as core operational methods, including against civilians.)

It does not (as stated) apply to the “Content that glorifies violence or the perpetrators of a violent act.”

Nor does it apply to the preexisting hateful conduct policy, “You may not promote violence against or directly attack or threaten other people on the basis of race, ethnicity, national origin, sexual orientation, gender, gender identity, religious affiliation, age, disability, or disease. ”

Of course, they have been inconsistent in enforcing the existing policy and given certain high-profile Twitter users a pass on it without an explicit exception, so one would expect that to continue with the new policies even where no explicit exception applies.
