What I was told by a tech rep for SplitFire plugs:

The spark develops at all "sharp" edges of the electrode, therefore if you have multiple sharp edges you will get a spark with quicker response time. Splitfire had given the parts shop where I worked a cool video of how this works.

The Splitfire has the V-tail electrode, AC has their Rapidfire (with a circle of serrated edges around the center electrode), Bosche has the DTC (triple electrode) and the +4s, and Motorcraft has a platinum with multiple electrodes...
