When too full it becomes easier for oil to get through the AOS and into the intake where it is then burned along with the air/fuel mixture. Too much oil can cause misfires and damage the catalytic converter, and "more" too much oil can hydro-lock the cylinder and destroy the engine.
I overfilled my oil just like that before my first track day, blew a huge smoke bomb, got a flashing CEL, engine cutting out, scared me to death, when I got home I dropped the oil filter canister and installed a new filter/o-ring (buying just a new o-ring was about the same price as a new filter which comes with the o-ring). This dropped my oil right down to just below the full mark and all was good
