The article isn't arguing that clipboard state should be part of the undo system, it is arguing that cut shouldn't touch clipboard state. In the "Side effects" section they mention if you want the contents to go to the clipboard, then you should use copy instead of cut.

If it doesn't change the state how do I cut and paste between programs? And is 'paste' now using the clipboard half the time but not the other half?

Yes exactly, cut (and pasting a cut) is entirely within the same app. If you want to put something in another program you would have to copy.

Not saying I would prefer it, just explaining what the article says.
