Yes, effectively all must be in OVERRIDES for the assignment statement to take effect. > E.g.

I would have thought that the value would have been "last one" however experimentation shows that "both" is what you actually get. I'm not exactly sure why. In practice I don't think we hit this kind of situation too often though, i.e. a mix of double and single overrides where the single override needs to take precedence.
