I would tend to agree with this. I might be working from home but that doesn't mean that I want work to bleed into all of my waking hours.

Nobody at work would mind if I needed to pop out during the day or do something, but equally, I think it's important to have some boundaries where I can turn the computer off after a certain time and not think about work. I certainly wouldn't want to be going back to it at 9pm unless there was a good reason to.
