The relief valve in the pump dumps the excess oil back into the pan.
The relief valve in the filter simply allows the pressurized oil from the pump to bypass the filtration media, but it is still pumped through the engine. This is a safety feature to prevent oil starvation due to clogged filters. Dirty oil getting to the engine is better than no oil at all.
Other than that I have to agree with everything else you've stated in this thread.
