The checklists bring the aircraft back to a known state.
One 777 pilot commented to say that this issue should have been caught by at least two checklists, implying that neither checklists had been followed.
Tangentially: if my 2006 Mercedes is reset (battery disconnected) it needs to idle for 20 minutes to re-learn the idle pattern. The vehicle then needs to be driven around for a bit to re-learn driving patterns. I wonder if there are similar settings on a 777 that would need to be preserved between 'resets'.

It provides a procedure that can be followed to put it to a known state, but its existence does not put it into a known state, with certainty. A reset puts it into a known state, with certainty. That known reset state probable wouldn't be useful, but can be set to be least-damaging, where a checklist can then be used to then put it into a "good" state. My assumption is that many planes don't allow a reset to be trivial, since levers and whatnot are involved. I also assume the FAA/military has done research into this and, probably, found that requiring a manual checklist resulted in stricter adherence to the checklist.
