This isn't wrong, but it is a simplistic model of one layer of depression, which can be a pragmatic way to look at it for some people during some periods, typically the most severe periods. I've suffered from severe depression for my whole adult life, and I am thankful that I haven't had a psychiatrist who subscribed to the medical model as an absolute, in many years. The big picture of depression can indeed be about your life, and no psychiatrist I've seen in the past 15 years has failed to acknowledge that. It's well known that major depression often follows major life stresses such as divorce, breakups, deaths, trauma, other illnesses, and so on. I've never found it fruitful to make it either all about the brain, or all about your life. It's rather a feedback loop between the two. The very nature of subjectivity makes it almost nonsensical to try to distinguish between your mind and your life, from your own perspective. And there's a reason treatment almost always includes talk therapy. I've always been able to articulate what my depression is about. Some people can't. It's just not so clear cut.
