You mentioned the behavior of L and C, which refers to the way the *component* represented by C and the *component* represented by L react. It is in your context that I used the term L. Now, apparently, you have changed the context to exclude consideration of the component (which will sometimes lead to incorrect analysis) and to restrict the term to have it refer to the property only. Therefore, we did not refer to the same thing with the term L.
What I referred to is a circuit element that can saturate, as per the definition for inductance.
I don't know where you came up with the above "rules" or whatever you want to call them. If, in solving a problem with an inductance, (specifically in this case, the effects of DC on an R,L,C load impedance) no consideration is given to saturation, the solution can be erroneous. Very specifically for the op's question, the possibility of saturation *must* be considered, even though the question did not include the word inductor. I think those rules, or whatever you call them, are not correct.
