My personal take is that the big things to note are:
1. Reducing symptoms of depression is not the same thing as treating depression.
Thus, if you exercise and it works for you to reduce the symptoms, you aren't "better," you just aren't feeling as depressed. This is valuable in its own right, as the symptoms of depression can interfere with you seeking actual treatment... But it is not helpful if you think you're better, stop exercising for some reason, and fall back into depression again, possibly with a side-order of pessimism that nothing seems to work.
2. Exercise is not more effective than psychological or pharmacological therapies.
Although they say there are only a few trials to establish this, I personally feel it's quite safe to assume that it is not more effective, and as per 1 above, that it can be harmful to take an "either/or" approach to exercise and other therapies. Until someone shows me research saying that exercise in conjunction with therapy is worse than therapy alone, I personally try to do both.

The uncomfortable truth about exercise is that a large number of people with mood disorders self-medicate their symptoms with endorphins. When that is used as an alternative to therapy, it may be harmful.
