This is similar to my experience, but there have been situations that are similar to what the article posted. Usually however, those are weeded out by the time the deployment to production comes around.

In that case, the QA team is already testing off the feature branch and when they're done testing, you probably don't need a cleanup branch as you've tested the case where you're going to not use it.

It seems that the method posted in the article would be very useful for when you have a strict release cycle with versioning/features in place and you know with pretty good certainty when you are either going to sunset an old feature or require all users to be on the new feature. In that regard, I could see this working very well.
