Companies selling tasers/stun guns advertise that the electricity will not travel through one person to another (ie if you tase an attacker who is grabbing you). How is this possible?

I've been looking at tasers and stun guns online and just read this on a website selling self defense products: "Should the attacker be touching you, the current will NOT pass to your body"
I'm having a hard time wrapping my mind around this and want to be sure that this claim isn't false advertising.

The current will take a path between the two barbs or prongs that make contact with the target.  If you somehow managed to stick an attacker with one barb and yourself with the other nothing would happen until you touched each other and completed the circuit.  It is the same reason lightning travels down a lightning rod and not in several laps around a wood frame house.  Path of least ohmic resistance.
