Changing Filament

No AMS. I can and have changed filaments by using the Unload function on the menu. Wait till it heats up, and you just pull back on the filament and it comes out. Which it does, though sometimes, it is a bit difficult to get the filament to release.
So today, I was installing hardened gears in my Extruder and was looking at the filament cutter for the first time. It looks like it was designed to be pushed to cut the filament.
So, am I supposed to be pushing the filament cutter on the Head when I am changing Filament? Because I have seen no reference, anywhere, to using the filament cutter on the Head.

No it pushes it against the side of the frame when you press unload.
