If properly installed, it will work just fine. You shouldn't strip or loosen a cog. My thought is that since the cogs are threaded on, the will most likely be within a couple degrees of each other, so unless they and the hub are machined perfectly, one cog will be doing more propelling and one will be doing more braking.
