In the study, the participants reduced activity for a period of 14 days, with the results being fully reversed after 14 days of resuming normal activity. So I read the quoted recommendation above is to avoid sedentary periods that are on the same order of magnitude (multiple days) vs. avoiding sedentary periods within a single day.
An anecdote: I had a short term knee issue that kept me off my mountain bike for most of the summer. What I didn't do was figure out a replacement activity for the 6-8 hours / week that I used to ride. I just did ... nothing and that had the predictable effect. Now that I'm recovered and riding 6-8 hours / week again, everything is returning back to normal.
