After thousands of cycles, the switch contacts get impinged on by their brothers and start to fail. We press mouse switches with our finger rather lightly. IF you take a disconnected or unhooked or bettery removed mouse and do this keypress operation, you should also press on that switch slightly harder than you do in use. What you are doing is burninshing the contacts against each other.
There is no debounce on logi mice, at least not the old ones. I have had several that would multi-count keypresses. And not do so if the keypress is more firm.
It may be that the driver 'sees' the noisey key and has no circuitry to filter that and sends two presses to the OS.
I doubt much debounce at all, since gamers do not like any form of latency.
That would be for resetting software? Does that
