Pretty sure the idea is that potassium mixes with an ionisation agent  which essentially ‘fast burns’ inside the lit flame. Ie. You get a non sustainable flame out at the source where the fire self extinguishes through the loss of surrounding oxygen.

Essentially, rather than flood the entire room with oxygen starving gas instead flood the room with something that will react to an ignition point and cause it to burn out before it spreads.

Wikipedia seems to go into the specifics: https://en.wikipedia.org/wiki/Condensed_aerosol_fire_suppression
