In terms of the summary explanation that I quoted above it would seem that the temporary insurance covers the liabilities of the PERSON they are covering.
Dual insurance of vehicles is very common indeed. Where I to borrow your car and drive it it would be been driven under my policy extension (driving other vehicles) whist still insured by your policy. Should anything happen to it whilst I am driving it my policy will cover my LEGAL MINIMUM liabilities (most extensions only being 3rd party) Any further liabilities (value of your car) would be for you to try and recover from me.
This temporary insurance just seems to be a slightly more comprehensive version of that type of cover for drivers without their own policies.
the big point here is 'TRY' and recover, there is a knowledge when someone lends you a car to drive on your 3rd party extension that if you trash car, then its not insured, and would be down to you to sort/walk away from ( there is legally no responsibility to reimburse AFAIK, as car has been lent in full knowledge (unless some agreement is in place B4) temporary insurance seems to muddy the waters, as the owner of the vehicle is led to believe this is beyond 3rd party extension and 3rd party is effectively fully indemnified for any occurrence, truth may be somewhat different.
Perhaps I'm looking for problems, or playing devils advocate, I always lend my car on the acceptance that if its trashed, then so be it, with anything, my philosophy is;-
only lend what you can afford to loose, and only borrow what you can afford to replace
