Pascs, most of the starters today might work the way you described but I guess there is (used to be) also a type of starters that used an "Inertia" Starter Motor. The gear was plunged into the flywheel ring gear by the inertia of the gear and the sudden acceleration of the motor. In this type starter there is no lever/plunger mechanism.
That a pretty old style, I don`t think they are used much any more, maybe on really cheap cars ? The problem with them used to be that although cheap to make the worm thread on the shaft that the gear got flung up got dirty and often jammed. If it jammed on the way up is was annoying but hitting the starter with a lump of wood used to fix it (funny how the fix is always the same). If it jammed even momentarily at the top whilst engaged and the engine had started, the harder flywheel teeth would strip lumps out of the gear.
