I am describing a bypass valve
and some "bypass filters".
Some full flow oil filter designs have a bypass valve, and anti-flowback valve, integral to the filter and when the filter becomes clogged, it allows unfiltered oil to prevent oil starvation of the engine.
Some full flow oil filter designs have a bypass valve on the engine to accomplish the same concept. This design also has an anti-flowback valve located on the engine.Since I did not see either a bypass valve or anti-flowback valve on the filter cartridge, I suspected the latter.
Some two-stage or bypass filters have a "fine" full-flow and an "ultra-fine" bypass section. Some have a "fine" full-flow and "coarse" bypass so that there is at least some filtration of the oil rather than un-filtered. Given what I see in the filters, I suspected the latter in this case also.
Now I haven't studied the oil system on this car but maybe someone has. You tell me.............
