Just some background, my father owns and operates his own auto body business, so this is where my knowledge comes from. To answer your question, yes and no. When they say you can't file another claim on the car, they mean a couple things: 1) you can't file any sort of claim in relation to the damage that was caused by Derecho (assuming hail damage etc). They will have pictures of the damage on file. 2) That does NOT mean you cant ever make a claim ever again though. In your example, if you total your car, they still are required to give you full out to replace your car at its value of the time accident (miles and year of vehicle come into play). The real battle you will fight will be if say you get into a much smaller accident. The insurance company is gonna be a real pain in the a$$ and try not to pay to fix things that had previous damage on them and will say "oh that damage was from Derecho and not the one you just got into" Obviously if you have a good auto body shop they will go to bat for you.
