Not a problem at all. It's actually better than when horizontal. When horizontal the cutter will try to fling the part just the same with exactly the same consequences if tool gets trapped. Even when horizontal the required parts need to be held securely other wise it's a lottery if they will be damaged or not. 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.
