The view matrix is the result of the ray tracing from the calculation points to the emitter (window/skylight, usually), and the daylight matrix is the result of tracing rays from the back side of the emitting surface to the sky/sun. The ambient settings matter for both, but you are right that they tend to be more aggressive for the VMX than the DMX. Some of the code may not make this seem obvious, as I recall, WRT some of the variable names I used. Silly you, trying to make sense of how this thing works by actually reading my spaghetti code (although the comments are usually good for a laugh or two). If you want to be more specific about where the confusion lies, I can try to clarify.
