Waste parts can be left lose but it's a lottery to what happens with them, they too can trap tools.
Being vertical the lose part drops away far easier than when in horizontal position and if for any reason it does clash with tool it gets flicked away far easier.
Also because most of the chips etc are falling away then there's virtually no chips clogging the slot again leaving the part to be ejected easier.

Put it this way it's not snapped any yet or even remotely looked like doing and it's cut plenty of Aluminium, Brass, copper, wood, plastic since being on the wall.
The cutters are lasting longer, the finish is better due to virtually no chip re-cutting and I need much less blown air to clear the remaining chips and best of all 90% the chips fall neatly into a bin on the floor.
Interesting to here what actually happens in practice.
I only cut wood, so the edges might get dinged falling on the floor. Although I tend to used the 'onion skin' method, and break out the parts after cutting.

I did think about it before I posted, and thought the cutter would be fine most of the time, but the the cut finished under the part, then the part would fall on the cutter bit.

Luckily I've not had any trouble with broken bits yet (I know I shouldn't say that) but I have seen the warnings from the bit suppliers about parts moving when cut free.
