Both 2.7 and 3.4 have a special status in that they are the latest of their branches. They will always be included. The author is writing for people who are interested in what they have to do to support pytyhon 3. People want to know: I already have to support 2.7 and 3.4 to 'do the right thing' according to the plan. Is that sufficient or should I worry about supporting more? This is very similar to the process web developers go through in deciding which browsers to support and when to cut off support.
