According to this article, the study found those who watch 5 or more hours of TV a day while sitting were 65% more likely to lose mobility in the period tested than those who watch < 2 hours per day, controlling for all other variables. I am skeptical the study was able to control for all other variables. Maybe those who watch 5 or more hours of TV a day are less likely to get activity during the day e.g. from taking the stairs, making dinner, chores, etc. To be frank, these sound like exceptionally lazy humans. They may be less likely to cook for themselves and eat healthy meals, or to take good care of themselves in other ways also. It's hard to control a study like this for all possible complicating factors. What is clear is that if you're sitting and watching TV with all your free time instead of being active, that's probably not healthy, but hey, it's your life.

Sure it's lazy, but I'm asking myself how it's even possible. If you work full time as in the example, how do you even squeeze in that much TV watching between family and various chores.

The study population was 50-71 years old - for most people, those are empty nest years (no kids in the house), and far less likely to be doing unpaid overtime to try to advance a career.
