Due to the aerosol duster valving design, they generally can only be sprayed right-side-up or, at most, a 45º angle. Under high pressure, the propellant is mostly liquid, with the empty part of the can filled with vapor. When you spray an aerosol duster, the vapors of the propellant are expelled. As you rotate the can, the liquid starts to spray out and at a very low temperature (as low as -60ºF / -51.5ºC). Techspray® offers Vortex 360, which is specifically designed to spray only gas as you rotate the can. As a side note, this also explains why it is a bad idea to shake up a can of duster before use, as is the habit of using spray paint. If you shake the duster, the liquid propellant is more likely to sputter out as you start spraying.
